Chemical Structure

Ornidazole Impurity 90 CAS CATO-C4X-133190 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 201.61 g/mol gives Ornidazole Impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ornidazole Impurity 90 (CAS CATO-C4X-133190), a pharmacopoeial impurity reference standard (molecular formula C7H8ClN3O2, MW 201.61 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ornidazole Impurity 90 (C7H8ClN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 201.61 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 Ornidazole Impurity 90 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.
