Used primarily as a reference standard or impurity marker in pharmaceutical quality control, this compound plays a critical role in the analysis and purification of Dabigatran, an anticoagulant drug. It helps in validating analytical methods such as HPLC and LC-MS to ensure the purity, stability, and consistency of Dabigatran formulations. Due to its structural similarity to the active pharmaceutical ingredient, it is essential for identifying degradation products and monitoring synthesis by-products during manufacturing. Its presence in trace amounts is closely monitored to meet regulatory requirements for drug safety and efficacy.
