Used primarily as a reference standard in pharmaceutical quality control, this compound serves as a key impurity marker in the synthesis and analysis of dasatinib, a tyrosine kinase inhibitor used in cancer treatment. It helps in validating analytical methods such as HPLC and LC-MS for purity assessment and stability testing of dasatinib formulations. Its presence is monitored to ensure drug safety and compliance with regulatory guidelines. Additionally, it supports process optimization during manufacturing by identifying degradation pathways and by-products.
