Used primarily as a reference standard or impurity control in the pharmaceutical industry during the synthesis and quality testing of dabigatran, an anticoagulant drug. It helps ensure the purity, safety, and consistency of the final drug product by allowing identification and quantification of related substances in analytical procedures such as HPLC and mass spectrometry. Its presence is monitored to assess degradation pathways and process-related impurities in the manufacturing of dabigatran etexilate.
