Sulfamethizole-d4

Sulfamethizole-d4 is intended for use as an internal standard for the quantification of sulfamethizole (Cay-23355) by GC- or LC-MS. Sulfamethizole is a broad-spectrum sulfonamide antibiotic (MIC90s = 1.25-5,000 µg/ml against clinical isolates of E. coli and K. pneumoniae). It inhibits dihydropteroate synthase, an enzyme involved in folate biosynthesis. Formulations containing sulfamethizole have previously been used to treat urinary tract infections.Formal Name: 4-amino-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzene-d4-sulfonamide.
