4-Methylthiosemicarbazide is a sulfur-containing organic compound widely used as a pharmaceutical intermediate and analytical reagent. With a melting point of 135-138°C (lit.) and density of 1.2±0.1 g/cm³, it serves as a key building block for heterocyclic compounds in medicinal chemistry. The material exhibits solubility in alcohol and slight solubility in water. Storage should be in airtight containers at room temperature, protected from moisture and light. Safety precautions include wearing protective gloves/eyewear due to acute oral toxicity (GHS Category 2, H300). Its thiosemicarbazide structure enables versatile applications in coordination chemistry and bioactive molecule synthesis.
