2,4-Dimercaptopyrimidine (Dithiouracil) is a sulfur-containing heterocyclic compound with applications in pharmaceutical synthesis and material science. This compound exhibits a melting point of 279-281°C (dec.) and predicted boiling point of 225.6±23.0°C at 760 mmHg. With a density of 1.5±0.1 g/cm³ and pKa of 8.46±0.10, it serves as a versatile building block for metal coordination complexes and bioactive molecules. The material should be stored in sealed containers under inert atmosphere due to sensitivity to oxidation. Safety precautions include wearing protective equipment as it may cause skin/eye irritation (GHS Category 2). Its unique structure enables applications in nucleoside analogs and as a ligand in transition metal catalysis.
