Desmethyl Celecoxib is primarily used in research settings as a metabolite of Celecoxib, a well-known COX-2 inhibitor. Its applications are largely focused on pharmacological and toxicological studies to understand the metabolic pathways and biological effects of Celecoxib. Researchers utilize Desmethyl Celecoxib to investigate its role in inflammation and pain management, particularly in assessing how the body processes and eliminates the parent drug. Additionally, it serves as a reference standard in analytical chemistry for drug testing and monitoring, ensuring accurate measurement of Celecoxib and its metabolites in biological samples. Its study also contributes to the development of safer and more effective therapeutic agents by providing insights into drug metabolism and potential side effects.
