Chemical Structure

Phoxim Impurity 6 CAS 14816-16-1 chemical structure

Description

Structurally, Phoxim Impurity 6 (C10H11N2O3PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 270.24 g/mol, it falls into the medium-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).

CATO supplies Phoxim Impurity 6 (CAS 14816-16-1), a pharmacopoeial impurity reference standard (molecular formula C10H11N2O3PS, MW 270.24 g/mol) used for the identification and quantification of trace impurities in APIs.

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 Phoxim Impurity 6 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.
