Chemical Properties

yellow crystalline powder

Uses

Thioacetanilide (N-Phenylthioacetamide) is a thioderivative of acetanilide that exhibits Z/E isomer preference and solvent dependence[1].

General Description

Metabolism and acute toxicity of thioacetanilide has been studied in rat. Thioacetanilide undergoes nucleophilic addition reaction with superoxide ion in dimethyl sulfoxide.
