Thiosemicarbazide is a vitamin B6 antagonist with anti-acne activity. Thiosemicarbazide is also a well-known source in the synthesis of heterocycles, and its derivatives have potential anticancer activity. Thiosemicarbazide (TSC: HL1) reacts with metal salts, urea (U), to prepare Co(II) and Cu(I) metal complexes. Thiosemicarbazide is also used in the fields of media communications and optical storage, and in the spectrophotometric detection of metals .
