Sulfamethoxazole-13C6（Cat No.:S000518） is an isotopically labeled version of sulfamethoxazole, where six of its carbon atoms are substituted with the stable isotope carbon-13 (13C). Sulfamethoxazole is a commonly used antibiotic in the sulfonamide class, effective against a broad spectrum of bacterial infections and often combined with trimethoprim to enhance its antibacterial efficacy. The incorporation of  13C in sulfamethoxazole-13C6 enables a detailed investigation of its metabolic pathways and pharmacokinetics through more precise and distinguishable tracking methods. This is particularly beneficial in studying the drug’s behavior in complex biological systems and optimizing dosing strategies in clinical settings.
