Chemical Structure

Chlorpromazine Impurity 7 CAS 28867-76-7 chemical structure

Description

Based on its molecular formula C14H12N2, Chlorpromazine Impurity 7 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Chlorpromazine Impurity 7 (CAS 28867-76-7), a pharmacopoeial impurity reference standard (molecular formula C14H12N2, MW 208.26 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
