Nintedanib Impurity N3 CAS CATO-C4X-12663 chemical structure

Description

CATO manufactures Nintedanib Impurity N3 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Nintedanib Impurity N3 (CAS CATO-C4X-12663) is a certified pharmaceutical impurity reference standard with the molecular formula C30H31N5O4 and a molecular weight of 525.60 g/mol.

Nintedanib Impurity N3 (C30H31N5O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
