Chemical Structure

Chlorphenamine Impurity 22 CAS 4584-46-7 chemical structure

Description

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 supplies Chlorphenamine Impurity 22 (CAS 4584-46-7), a pharmacopoeial impurity reference standard (molecular formula C4H10ClNHCl, MW 144.04 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Chlorphenamine Impurity 22 (C4H10ClNHCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 144.04 g/mol, it falls into the low-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.

As a certified reference material (CRM), Chlorphenamine Impurity 22 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
