Used primarily as a reference standard in pharmaceutical quality control, this compound serves as a key impurity marker in the analysis of edoxaban, an oral anticoagulant. It aids in the identification, quantification, and monitoring of impurities during the manufacturing and stability testing of edoxaban formulations. Its presence helps validate analytical methods such as HPLC and LC-MS, ensuring drug purity, safety, and consistency in final dosage forms. It is also used in forced degradation studies to assess the robustness of analytical procedures and the stability of the active pharmaceutical ingredient under various stress conditions.
