(Phenylthio)acetic acid Chemical Properties, Uses, Production

Chemical Properties

White solid

Uses

(Phenylthio)acetic acid is a reactant in the preparation of benzoxazoles, benzimidazoles, and benzothiazoles, which exhibit antimicrobial activity.

Application

(Phenylthio)acetic Acid (PTAA) is used for preparation of various PhS-containing compounds, such as 3- or 4-hydroxy-2-(phenylthio)alkanoic acids, 4-oxo-2-(phenylthio)alkanoic acids, and α-phenylthio-β-lactams.

Preparation

(Phenylthio)acetic acid is prepared by the substitution reaction of sodium chloroacetate with sodium benzenethiolate, or by the treatment of bromoacetic acid with thallium(I) benzenethiolate.[1]
