General description
Sulfamethoxazole is a bacteriostatic antibiotic used in treating coccidiosis, diarrhea and gastroenteritis in humans and is also a known veterinary drug. Sulfamethoxazole in combination with trimethoprim is effective in treating pneumonia. Sulfamethoxazole acts by blocking the folic acid metabolism to produce synergistic antibacterial activity.
Application
Sulfamethoxazole may be used as a reference standard for the determination of the analyte in:
- Bovine milk by high-performance liquid chromatography method.
- Pharmaceutical formulations and biological samples by capillary electrophoresis (CE) with end-column electrochemical detection (EC).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
