Chemical Structure

Albendazole Impurity 20 CAS 1149360-33-7 chemical structure

Description

CATO supplies Albendazole Impurity 20 (CAS 1149360-33-7), a pharmacopoeial impurity reference standard (molecular formula C13H17N3O2S, MW 279.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Albendazole Impurity 20 (C13H17N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 279.36 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Albendazole Impurity 20 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.
