Valsartan Impurity 122 CAS 1335138-31-2

Description

The occurrence of Valsartan Impurity 122 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Valsartan Impurity 122 (CAS 1335138-31-2), a pharmacopoeial impurity reference standard (molecular formula C40H39N5O2C2H2O4, MW 711.82 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C40H39N5O2C2H2O4, Valsartan Impurity 122 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 711.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Valsartan Impurity 122 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.
