CAS 59-40-5 — Sulfaquinoxaline (4-amino- N-2-quinoxalinylbenzenesulfonamide)

Sulfaquinoxaline (4-amino-*N*-2-quinoxalinylbenzenesulfonamide) is a synthetic sulfonamide antibiotic and coccidiostat used primarily in veterinary medicine to treat coccidiosis in poultry, cattle, and other livestock. It inhibits bacterial and protozoal growth by disrupting folic acid synthesis. This white to off-white crystalline powder has a CAS number of 59-40-5, with the molecular formula C14H12N4O2S and a molecular weight of 300.34. It is stable at ambient storage conditions but requires careful handling due to its hazardous classification (Signal Word: Danger). Molekula supplies Sulfaquinoxaline from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
