Product Information

Sulfamethoxazole is a widely recognized sulfonamide antibiotic, primarily used in the treatment of bacterial infections. Its unique structure, featuring a 5-methyl-1,2-oxazole moiety, enhances its efficacy against a broad spectrum of Gram-positive and Gram-negative bacteria. This compound is particularly valuable in the pharmaceutical industry, where it is often combined with trimethoprim to create a synergistic effect, resulting in a potent treatment for urinary tract infections, respiratory infections, and certain types of pneumonia.

In addition to its medicinal applications, sulfamethoxazole is also utilized in veterinary medicine, providing effective treatment for infections in animals. Researchers appreciate its role in microbiological studies, where it serves as a model compound for investigating bacterial resistance mechanisms. With its established safety profile and effectiveness, sulfamethoxazole remains a vital tool in both human and veterinary healthcare, making it an essential compound for professionals in the pharmaceutical and research sectors.
