Medchemexpress LLC Sulfamethoxazole-13C6 | 1196157-90-0 | 99.9% | 5 MG
SDP

Sulfamethoxazole-13C6 is a 13C labeled sulfonamide antibiotic. It inhibits bacterial folate metabolism by competing with 4-Aminobenzoic acid (PABA) to act on dihydropteroate synthetase and dihydropteroate reductase. This compound can be used for the study of urinary tract infections (UTIs), prostatitis, and bronchitis. It also serves as a tracer and an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
