Used primarily as an impurity reference standard in pharmaceutical quality control, particularly in the analysis of tranexamic acid-based medications. It helps in identifying and quantifying degradation products during stability testing of formulations. Its presence is monitored in high-performance liquid chromatography (HPLC) and mass spectrometry methods to ensure drug purity and safety. Also utilized in research settings to study the degradation pathways of tranexamic acid under various storage or stress conditions.
