4-Phenyl-3-thiosemicarbazide is an important sulfur-containing organic compound widely used as a biochemical reagent and pharmaceutical intermediate. This compound demonstrates a melting point of 138-140°C (lit.) and exhibits characteristic reactivity in Schiff base formation with aldehydes/ketones. It serves as a key precursor for heterocyclic compounds with antimicrobial and antitumor activities. The material should be stored in sealed containers at room temperature, protected from light and moisture. Safety precautions include wearing protective equipment due to acute oral toxicity (GHS Category 2) and potential skin/eye irritation.
