3-Sulfanilamido-6-oxopyridazine, also known as sulfapyridine, is a synthetic chemical compound belonging to the sulfonamide class of antibiotics. It is primarily used for the treatment of urinary tract infections, as it exhibits bactericidal activity against a wide range of gram-positive bacteria. The compound is characterized by its white crystalline appearance and is soluble in water. Sulfanilamido-6-oxopyridazine is a prodrug, meaning it is metabolized in the body to release the active sulfonamide compound, which inhibits bacterial growth by competing with para-aminobenzoic acid (PABA) for the synthesis of folic acid, an essential component for bacterial replication. Due to its broad-spectrum activity and relatively low cost, sulfapyridine remains a significant component in the treatment of various bacterial infections, although its use has been largely replaced by more modern antibiotics in many cases.
The CAS Registry Mumber 1456-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1456-34: (6*1)+(5*4)+(4*5)+(3*6)+(2*3)+(1*4)=74 74 % 10 = 4 So 1456-34-4 is a valid CAS Registry Number.
