Chemical Structure

Tenofovir alafenamide Impurity 97 CAS CATO-C4X-179797 chemical structure

Description

Tenofovir alafenamide Impurity 97 (CAS CATO-C4X-179797) is a certified pharmaceutical impurity reference standard with the molecular formula C21H29N6O5P and a molecular weight of 476.47 g/mol.

The molecular framework of Tenofovir alafenamide Impurity 97 (C21H29N6O5P) is characterized by a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Tenofovir alafenamide Impurity 97 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.
