N-(N-sulfanilyl-sulfanilyl)-sulfanilic acid amide, also known as sulfamethizole, is a synthetic sulfonamide antibiotic. It is a white or slightly yellow crystalline powder with a molecular formula of C12H14N4O4S2. N-(N-sulfanilyl-sulfanilyl)-sulfanilic acid amide is primarily used to treat various bacterial infections, particularly urinary tract infections, respiratory infections, and otitis media. Sulfamethizole works by inhibiting bacterial synthesis of dihydrofolic acid, which is essential for bacterial growth and reproduction. It is available in oral forms, such as tablets and suspensions, and is generally well-tolerated, although side effects like nausea, vomiting, and allergic reactions can occur. It is important to note that sulfamethizole is not effective against penicillin-resistant bacteria and should be used with caution in patients with a history of sulfonamide allergies.
The CAS Registry Mumber 599-77-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 9 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 599-77: (5*5)+(4*9)+(3*9)+(2*7)+(1*7)=109 109 % 10 = 9 So 599-77-9 is a valid CAS Registry Number.
