Product Description
Sulfamide (CAS 7803-58-9), also known as Sulfuric diamide or Sulfuryl diamide, is a simple organosulfur compound with a molecular formula of H?N?O?S and a molecular weight of 96.11 Da. It appears as a white to practically white crystalline powder, free from visible impurities. As a versatile chemical intermediate, it possesses excellent stability and reaction activity, widely used in pharmaceutical R&D (as a key intermediate for famotidine), pesticide and dye synthesis, polymer production, and scientific research fields.
1. Physical Properties
White to practically white crystalline powder, free from visible impurities; melting point 90-92 °C, density 1.611 g/mL at 25°C; soluble in hot water (50mg/mL) and ethanol, insoluble in cold water, ether and benzene; moisture-sensitive, easy to absorb moisture in air.
2. Chemical Properties
A simple organosulfur compound with a structure of H?NSO?NH?, stable in acidic, neutral and alkaline aqueous solutions at room temperature[1]. It can absorb dry ammonia to form colorless ammonia complexes, and has good compatibility under various reaction conditions, participating in transition metal-catalyzed cross-coupling, amide/ester formation, nucleophilic alkylation and other reactions[1][6]. It is a valuable building block in chemical synthesis, and its derivatives have carbonic anhydrase inhibitory and urease inhibitory activities.
3. Storage & Safety Properties
Storage: Store in an inert atmosphere at room temperature, keep sealed and dry, avoid moisture absorption; avoid mixing with strong oxidants, strong acids and strong bases[4]. Safety: May cause skin and eye irritation, and may have adverse effects on the respiratory system; avoid inhaling dust and direct contact with skin and eyes; wear protective gloves and goggles during operation[2][4]. Transportation: Comply with relevant regulations, use sealed packaging to prevent moisture and leakage, and can be transported by conventional land transportation.
