Thiobenzoic acid is a sulfur-containing carboxylic acid derivative with a characteristic foul odor. This reactive compound exhibits a melting point of 15-18°C and boiling point of 222°C (lit.), with a density of 1.174 g/mL at 25°C and refractive index of 1.602-1.608. Primarily used as a thioacylating agent in organic synthesis, it serves as a key intermediate for pharmaceuticals and agrochemicals. The material is moisture-sensitive and decomposes in water, requiring storage under inert atmosphere at 2-8°C. Safety precautions are critical due to its corrosive nature (GHS Category 1B) and ability to release toxic H₂S gas upon decomposition.
