(Methylthio)acetic acid Chemical Properties, Uses, Production

Chemical Properties

Clear colorless to pale yellow liquid

Uses

(Methylthio)acetic acid may be used in the synthesis of (5S,6S,8S)-8-acetoxy-6-(3,4-methylenedioxyphenyl)-1-[(methylthio)-acetyl]-1-azaspiro[4.4]nonane.

Definition

ChEBI: (methylthio)acetic acid is a sulfur-containing carboxylic consisting of thioglycolic acid carrying an S-methyl substituent. It has a role as a xenobiotic metabolite. It is a sulfur-containing carboxylic acid, a monocarboxylic acid and a methyl sulfide. It is functionally related to a thioglycolic acid. It is a conjugate acid of a (methylthio)acetate.

General Description

Formation of complexes of methyl thioacetate and copper(II) has been investigated. (Methylthio)acetic acid is an irreversible inhibitor of sarcosine oxidase and is effective in preventing the complete enzyme inactivation during modification.
