Martin Sulfurane was a renowned scientist and inventor who made significant contributions to the fields of chemistry and engineering. Born in the early 19th century, Sulfurane was a self-taught prodigy who began experimenting with chemistry at a young age. He eventually attended the University of Paris, where he received a degree in chemistry.
Throughout his career, Sulfurane made numerous important discoveries and inventions. One of his most notable contributions was the development of a process for the manufacture of sulfuric acid, which is used in a wide range of industrial applications. He also developed a method for the production of sulfur dioxide, which is used as a bleaching agent and a disinfectant.
In addition to his work in chemistry, Sulfurane also made significant contributions to the field of engineering. He invented a steam-powered engine that was used to power a variety of machines, including pumps and generators. This invention had a major impact on the Industrial Revolution and helped to drive technological progress in the 19th and early 20th centuries.
Sulfurane was also known for his philanthropic efforts. He donated a large portion of his wealth to fund scientific research and education, and he founded several institutions dedicated to the advancement of science and technology.
In conclusion, Martin Sulfurane was a remarkable scientist and inventor who made significant contributions to the fields of chemistry and engineering. His work had a lasting impact on society and helped to drive technological progress in the modern world.
Pharos links directly only to those with that refer to specific chemicals. It is a colorless corrosive gas that releases dangerous HF upon exposure to water or moisture. It provides information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, nanomaterials, and related areas. The main bismuth oxidation states are Bi III and Bi V as in all higher group 15 elements. What are the asterisks in the Hazard List table? The information of the atoms, bonds, connectivity and coordinates included in the chemical structure of Martin Sulfurane can easily be identified by this visualization. Users take all responsibility for actions based on expired assessments. Additionally, it contains information on how chemicals are produced, and what building products they can be found in.
It is the responsibility of users to verify whether an assessment has expired. There are some distinctions between the GreenScreen and C2C thresholds that result in different color assignments that are under consideration for harmonization. The Martin Sulfurane molecule contains a total of 68 bond s There are 48 non-H bond s , 24 multiple bond s , 8 rotatable bond s , 24 aromatic bond s and 4 six-membered ring s.

Despite these unwelcome characteristics, this compound is a useful reagent for the preparation of organofluorine compounds, some of which are important in the pharmaceutical and specialty chemical industries. The carbon atoms in the chemical structure of Martin Sulfurane are implied to be located at the corner s and hydrogen atoms attached to carbon atoms are not indicated — each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds. Thiophenol is an organosulfur compound with the formula C 6H 5SH, sometimes abbreviated as PhSH.
It is managed by the U. It is widely used in the synthesis of organic and organometallic compounds. Why are these rating colors sometimes different from the GreenScreen or Pharos rating colors? It is the source of the physical properties and many of the synonyms for chemicals in Pharos. It is a white solid that is soluble in organic solvents. Expired assessments may not be used to make claims of any sort or receive credit under standards which incorporate GreenScreen. The prefix thio- implies a sulfur-containing compound and when used before a root word name for a compound which would normally contain an oxygen atom, in the case of 'thiol' that the alcohol oxygen atom is replaced by a sulfur atom. The health and environmental hazards in the hazard summary table have been associated with this substance in hazard lists developed by scientific bodies such as the US EPA or International Agency for Research on Cancer IARC.
The Jones oxidation is an organic reaction for the oxidation of primary and secondary alcohols to carboxylic acids and ketones, respectively. Minor contamination by thiophenol is responsible for the disagreeable odour associated with this compound. Related Research Articles Triphenylphosphine IUPAC name: triphenylphosphane is a common organophosphorus compound with the formula P C 6H 5 3 and often abbreviated to P Ph 3 or Ph 3P. Users must have a Pharos subscription to access the comparison, but you can still invite unregistered users, and they will show as "pending" until they register.

National Library of Medicine. The top table displays preliminary hazard ratings for individual endpoints based on the hazard lists a given chemical appears on. What makes a hazard high or low confidence? What are the C2C Hazards? A chemical formula of Martin Sulfurane can therefore be written as: C30H20F12O2S The chemical formula of Martin Sulfurane shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
Click on any hazard list name in the full Hazard Lists table for a detailed description and full list of chemicals associated with that list. Pharos has two additional rating colors - orange and purple - not used in the C2C or GreenScreen systems. Scientific hazard lists sometimes specify a chemical group such as trimethyltin compounds without a defined list of CASRNs. See the Less frequently, an asterisk may indicate a hazard is assigned because the chemical has been identified as a synonym of another chemical that has been specified by the hazard list. Email What is a GreenScreen Assessment? EPA, IARC, NSF International and independent parties offering peer-reviewed risk values.
Phenyl isocyanate is an organic compound typically abbreviated PhNCO. Add users by email above to share into this comparison. The chemical structures of thiophenol and its derivatives are analogous to phenols except the oxygen atom in the hydroxyl group -OH bonded to the aromatic ring is replaced by a sulfur atom. Full GreenScreen assessments trump results from List Translator scoring. In most instances, they indicate a hazard is assigned because the chemical is a member of a group. They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.
The first reported use of bismuth in organic chemistry was in oxidation of alcohols by Challenger in 1934 using Ph 3Bi OH 2. While sulfur-containing antibiotics save many lives, sulfur mustard is a deadly chemical warfare agent. The eChemPortal is an effort of the Organisation for Economic Co-operation and Development OECD in collaboration with numerous governments and NGOs. When iodine is ligated to an organic residue and electronegative ligands, hypervalent iodine compounds occur with a +3 oxidation number as iodine III or λ 3-iodanes or as a +5 oxidation number as iodine V or λ 5-iodanes. PPh 3 exists as relatively air stable, colorless crystals at room temperature. These iodine compounds are hypervalent because the iodine atom formally contains more than the 8 electrons in the valence shell required for the octet rule.
Its use has subsided because milder, more selective reagents have been developed, e. However, as used in the context of organic synthesis, the term iodane more specifically refers to organoiodine compounds with nonstandard bond number, making this term a synonym for hypervalent iodine. Nationality Almamater Knownfor Awards Alexander von Scientific career Institutions James Cullen Martin January 14, 1928 — April 20, 1999 was an American chemist. It dissolves in non-polar organic solvents such as benzene and diethyl ether. How can I learn more about the hazard lists? Known in the field as "J.

Organosulfur compounds are organic compounds that contain sulfur. Additionally, a red hazard rating in any one endpoint does not automatically mean that a substance will be x-assessed and targeted for phase-out, as exposure relevant to the endpoint may be deemed non-plausible for the substance depending on the material and product context in which it is being assessed. Phosphorus, Sulfur, and Silicon and the Related Elements. The ratings for the hazard lists used in this tool are based on Table 9 in the Material Assessment Methodology, Cradle to Cradle Certified Version 3.
