Tenofovir disoproxil Impurity 50 CAS CATO-C4X-107650

Description

The occurrence of Tenofovir disoproxil Impurity 50 is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tenofovir disoproxil Impurity 50 (CAS CATO-C4X-107650), a pharmacopoeial impurity reference standard (molecular formula C18H29N6O9PC4H4O4, MW 620.51 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Tenofovir disoproxil Impurity 50 (C18H29N6O9PC4H4O4) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 620.51 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 disoproxil Impurity 50 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.
