However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. umn class: Standard non-polar; Column length: 3 m; Column type: Packed; Start T: 42 C; CAS no: 74931; Active phase: SE-30; Data type: Kovats RI; Authors: Rudenko, G.I. ; Heo, J., Aroma of roasted sesame oil: characterization by direct thermal desorption-gas chromatography-olfactometry and sample dilution analysis, Am. (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. The source of the information is mentioned in the introductory sentence of the hazard statements. Substances listed in the EINECS, ELINCS, or NLP inventories. Substances may have impurities and additives that lead to different classifications. [Note: A liquid below 43F. In that case, the ATP (Adaptation to Technical Progress) number is displayed. Comparison of different fibers, J. Chromatogr. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. ; Cantwell, M.I. 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. If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. Structure, properties, spectra, suppliers and links for: butanethiol, 109-79-5, n-C4H9SH. ; Stern, D.J. In addition, thiols prepared from alkanes retain the -e in the name of the alkane—for example, butanethiol and ethanethiol as opposed to the alcohols butanol and ethanol. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. Aromatic thiols can be made from the amino compounds by way of the diazonium salts. Toxicol., 65(1), 2000, 34-39. ass: Standard polar; Column diameter: 0.32 mm; Column length: 60 m; Column type: Capillary; Heat rate: 5 K/min; Start T: 34 C; End T: 200 C; End time: 10 min; Start time: 3 min; CAS no: 74931; Active phase: DB-Wax; Carrier gas: He; Phase thickness: 0.25 um; Data type: Normal alkane RI; Authors: Schluter, S.; Steinhart, H.; Schwarz, F.J.; Kirchgessner, M., Changes in the odorants of boiled carp fillet (Cyprinus carpio L.) as affected by increasing methionine levels in feed, J. Agric. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. Food Chem., 47, 1999, 5146-5150. ass: Standard polar; Column diameter: 0.25 mm; Column length: 60 m; Column type: Capillary; Heat rate: 2 K/min; Start T: 40 C; End T: 200 C; Start time: 2 min; CAS no: 74931; Active phase: DB-Wax; Carrier gas: He; Data type: Normal alkane RI; Authors: Umano, K.; Hagi, Y.; Nakahara, K.; Shyoji, A.; Shibamoto, T., Volatile chemicals formed in the headspace of a heated D-glucose/L-cysteine Maillard model system, J. Agric. 1.14 ). The POPs Regulation bans or severely restricts the production and use of persistent organic pollutants in the European Union. A list of substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. 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. Food Chem., 40(5), 1992, 850-852. ass: Semi-standard non-polar; Column diameter: 0.32 mm; Column length: 60 m; Column type: Capillary; Heat rate: 3 K/min; Start T: 40 C; End T: 200 C; Start time: 5 min; CAS no: 74931; Active phase: SPB-5; Carrier gas: He; Phase thickness: 1.0 um; Data type: Normal alkane RI; Authors: Pinho, O.; Peres, C.; Ferreira, I.M.P.L.V.O., Solid-phase microextraction of volatile compounds in "Terrincho" ewe cheese. Gas Chromatogr., 6, 1968, 203-217. umn class: Semi-standard non-polar; Column diameter: 0.25 mm; Column length: 50 ft; Column type: Packed; Start T: 67 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 the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. This reaction is expected to reduce the concentration of isothiocyanates in the cell and represents the first step in their metabolism/inactivation [180] (see Fig. (Gas, Liquid, None), Colorless gas with a disagreeable odor like garlic or rotten cabbage. 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. InfoCards are updated when new information is available. CopyCopied, LSDPWZHWYPCBBB-UHFFFAOYSA-N This information has not been reviewed or verified by ECHA, and may change without prior notice.
