설명

일반 설명

S-(Thiobenzoyl)thioglycolic acid (TBTGA) also known as (thiobenzoylthio)acetic acid is a reagent used for thiobenzoylation. It participates in the transformation of threonine into β-methylcysteine.

애플리케이션

S-(Thiobenzoyl)thioglycolic acid ((thiobenzoylthio)acetic acid) was employed as reversible addition-fragmentation chain transfer (RAFT) agent during the copolymerization of styrene and divinylbenzene. It was also employed as chain-transfer agent for the RAFT polymerizations of styrene, methyl methacrylate and butyl acrylate.
It may be used to synthesize the following:

• N-Thiobenzoyl-DL-threonine ethyl ester by reacting with DL-threonine.
• Thiobenzoic acid O-esters by reacting with alkoxides.
• N-Thiobenzoylamino acids by reacting with amino acids.
