White or off-white crystalline substances. They are soluble in alcohols and hot water but insoluble in cold water, ether and benzene. At room temperature, they can absorb dry ammonia gas to form colorless ammonia complexes. They are stable in acidic, neutral and alkaline aqueous solutions. Sulfonamide has the properties of stability, availability and compatibility in various reaction conditions, including transition metal-catalyzed cross-linking reactions, amide/ester formation reactions, nucleophilic alkylation reactions, etc. Therefore, sulfonamide compounds are the best reagent sources for sulfonamide groups in the later stage.

1.White or off-white crystalline substances. Soluble in alcohol, soluble in hot water, insoluble in cold water, ether and benzene.
2.At room temperature, it can absorb dry ammonia gas to form a colorless ammonium complex. It is stable in acidic, neutral and alkaline aqueous solutions.

It is used for manufacturing medicines, pesticides, veterinary drugs, dyes, etc. Sulfamides are intermediates for the production of the gastric medicine famotidine.
