Used primarily as a reference standard in pharmaceutical quality control and analytical testing, this compound serves as a key impurity marker in the production and purification of dabigatran, an oral anticoagulant. It helps in validating analytical methods such as HPLC and LC-MS for the detection and quantification of related substances in active pharmaceutical ingredients. Its presence is monitored to ensure drug purity, safety, and compliance with regulatory guidelines. Additionally, it supports stability studies and process optimization during manufacturing by identifying degradation pathways and by-products.
