Thiols show many reactions like those of the hydroxyl compounds, such as formation of thioesters and thioethers (sulfides). (Rus.

It is possible that a harmonisation is introduced through an amendment to the CLP Regulation.

If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard. The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter.

Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. Danger! This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.

This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). In that case, the ATP (Adaptation to Technical Progress) number is displayed. (Warsaw), 26, 1981, 109-113. umn class: Semi-standard non-polar; Column diameter: 0.25 mm; Column length: 50 ft; Column type: Packed; Start T: 27 C; CAS no: 74931; Active phase: Squalane; Carrier gas: He; Substrate: Chromosorb P; Data type: Kovats RI; Authors: Hively, R.A.; Hinton, R.E., Variation of the retention index with temperature on squalane substrates, J.

If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. Food Chem., 50, 2002, 2900-2907.

Agric. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. This article was most recently revised and updated by. Reacts vigorously or explosively with a wide variety of materials - consult a full MSDS data sheet before using.

REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. CopyCopied, LSDPWZHWYPCBBB-UHFFFAOYSA-N More information about CAS and the CAS registry can be found here. ; Ling, L.C., Broccoli storage under low-oxygen atmosphere: Identification of higher boiling volatiles, J. Agric. Toward oxidation, however, they differ profoundly from alcohols: whereas oxidation of an alcohol usually leads to a product in which the oxidation state of a carbon atom has been changed, oxidation of a thiol affects the sulfur atom. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. (Gas, Liquid, None), Colorless gas with a disagreeable odor like garlic or rotten cabbage. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). The molecular structure is based on structures generated from information available in ECHA’s databases. : C 10 ppm (20 mg/m 3 ), L-methionine + H2O -> methanethiol + 2-oxobutanoate + ammonium, L-methionine + H2O -> methanethiol + ammonium + 2-oxobutanoate, S-methyl-5-thio-alpha-D-ribose 1-phosphate degradation II, 1-(methylthio)xylulose 5-phosphate + a reduced electron acceptor -> 1-deoxy-D-xylulose 5-phosphate + methanethiol + an oxidized electron acceptor, L-methionine -> methanethiol + (2Z)-2-aminobut-2-enoate + H+, O-acetyl-L-homoserine + methanethiol -> L-methionine + acetate + H+.

According to the classification provided by companies to ECHA in CLP notifications this substance causes serious eye irritation, is a highly flammable liquid and vapour, causes skin irritation and may cause respiratory irritation. ents, alkali and alkaline earth metals, epoxides, hydrazines, ketones, lead, mercury (II) oxide, azo- anddiazo- compounds, copper, copper alloys, nitrides, organic peroxides,and a variety of other che

Incompatible with strong oxidizing ag Symp. Highly flammable - note low flash point. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. The EC Number is the numerical identifier for substances in the EC Inventory. If the substance is covered by more than one CLH entry (e.g. Abbreviated EtSH, it consists of an ethyl group (Et), CH3CH2, attached to a thiol group, SH. This information has not been reviewed or verified by ECHA, and may change without prior notice.

Anal. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. The lower aliphatic thiols are useful as warning odorants in fuel gases and are somewhat toxic. Chem. Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA.

[Note: A liquid below 43F. If at least one company has indicated that the substance classification is affected by impurities or additives, this will be indicated by an informative sentence.

Substances listed in the EINECS, ELINCS, or NLP inventories. Remove all sources of ignition from the working area.Safety glasses. Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. Updates? The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. When solutizers, such as potassium isobutyrate and sodium cresylate, are added to caustic soda, the solubility of the….

Thiols are among the odorous principles in the scent of skunks and of freshly chopped onions; their presence in petroleum and natural gas is objectionable because they have disagreeable odours, interfere with catalysts used in refining processes, and produce sulfur dioxide upon combustion.
