Methyl mercaptan Specification

The Methyl mercaptan, with the CAS registry number 74-93-1, is also known as Thiomethanol. It belongs to the product category of API intermediates. Its EINECS number is 200-822-1. This chemical's molecular formula is CH₄S and molecular weight is 48.11. What's more, its systematic name is methanethiol. Its classification codes are: (1)Mutation data; (2)TSCA Flag T [Subject to the Section 4 test rule under TSCA]. It is an intermediate in the manufacturing of jet fuels, pesticides, fungicides, plastics, synthesis of methionine. Moreover, its odor may cause nausea. It is also used in the production of intermediates of methane sulfonyl chloride and methylthio propanol. It should be sealed and stored in a cool, ventilated and dry place. Moreover, it should be protected from oxides and fire.
