N-Nitroso Dasatinib Impurity 1 is a chemical impurity that can be associated with the synthesis or degradation of dasatinib, a tyrosine kinase inhibitor used in the treatment of certain types of cancer. Impurities like N-Nitroso Dasatinib Impurity 1 are of significant concern due to their potential toxicity and regulatory implications. N-nitrosamines, in particular, have been linked to carcinogenic risks, making their detection, quantification, and control critical in pharmaceutical manufacturing. Ensuring that such impurities are minimized or eliminated is essential to maintaining the safety, efficacy, and compliance of dasatinib as a therapeutic product.
