Sulfanilamide (CAS 63-74-1) is white granular or powder crystal,odorless. Taste slightly bitter. Slightly soluble in cold water, ethanol, methanol, ether and acetone, soluble in water, glycerin, hydrochloric acid, potassium hydroxide and sodium hydroxide solution, insoluble in chloroform, ether, benzene, petroleum ether. It is topical anti-inflammatory drugs.
As a sulfonamide antibiotic, sulfanilamide functions by competitively inhibiting (i.e., by acting as a substrate analogue) enzymatic reactions involving para-aminobenzoic acid (PABA). PABA is needed in enzymatic reactions that produce folic acid, which acts as a coenzyme in the synthesis of purines and pyrimidines. Mammals do not synthesize their own folic acid so are unaffected by PABA inhibitors, which selectively kill bacteria.

1) Sulfanilamide is used in the pharmaceutical industry, is the main raw material for the synthesis of sulfa drugs
2) Sulfanilamide is an important intermediate of sulfa drugs.
3) Sulfanilamide has a wide antimicrobial spectrum, hemolytic streptococcus, neisseria meningitidis, staphylococcus aureus and other gram-positive and negative bacteria are antimicrobial effect.This product is a local drug, but since the part of the absorption of the wound.Used for hemolytic streptococcus, staphylococcus of trauma, infection, etc.Quickly can also be used to stop the bleeding.
