QYRLogo
Phthalylsulfathiazole API is the active pharmaceutical ingredient of a sulfonamide antibiotic, chemically termed N-(2-thiazolyl)-4-phthalimidobenzenesulfonamide. Historically used for intestinal infections, it competitively inhibits bacterial dihydropteroate synthase, disrupting folate synthesis. Currently limited to veterinary use or human preoperative prophylaxis in specific regions due to drug resistance and newer antibiotics. Manufacturing must comply with pharmacopeias (e.g., USP/EP), with strict impurity control (e.g., free sulfathiazole ≤0.5%). This off-white powder is poorly water-soluble and formulated into tablets or suspensions. Major suppliers are Asia-based, with noted risks of adverse effects (e.g., allergies, crystalluria) and tightening regulatory scrutiny.

Phthalylsulfathiazole API is the active pharmaceutical ingredient of a sulfonamide antibiotic, chemically termed N-(2-thiazolyl)-4-phthalimidobenzenesulfonamide. Historically used for intestinal infections, it competitively inhibits bacterial dihydropteroate synthase, disrupting folate synthesis. Currently limited to veterinary use or human preoperative prophylaxis in specific regions due to drug resistance and newer antibiotics. Manufacturing must comply with pharmacopeias (e.g., USP/EP), with strict impurity control (e.g., free sulfathiazole ≤0.5%). This off-white powder is poorly water-soluble and formulated into tablets or suspensions. Major suppliers are Asia-based, with noted risks of adverse effects (e.g., allergies, crystalluria) and tightening regulatory scrutiny.
