Afatinib

Afatinib Impurities

Afatinib impurities consist of process-related compounds, residual solvents, and degradation products formed under stress conditions such as hydrolysis, oxidation, and photolysis. As a tyrosine kinase inhibitor used in the treatment of non-small cell lung cancer (NSCLC), impurity profiling is essential to maintain therapeutic efficacy and patient safety. Degradation pathways typically involve cleavage of the quinazoline ring, oxidation of the aniline moiety, and hydrolytic breakdown of the acrylamide side chain. All impurities are structurally characterized and qualified in accordance with ICH guidelines for toxicological assessment and analytical validation.

Afatinib EP Impurities

Pharmacopeial and non-pharmacopeial Afatinib impurity compounds are available in compliance with European Pharmacopoeia (EP) specifications. These standards support analytical method development, impurity profiling, and long-term stability studies. EP traceable materials are supplied with validated analytical data, including purity, structural confirmation, and spectral characterization.

Afatinib Related Compounds

Structurally related compounds and synthetic analogs associated with Afatinib are included for use in impurity identification, toxicological qualification, and regulatory submission. These related substances are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations. They are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Afatinib Impurity Reference Standards

Afatinib impurity reference standards are provided with validated analytical data, including purity, NMR, MS, and full Certificates of Analysis. These standards are used in pharmaceutical research, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
