Propranolol Impurity 16 CAS 5234-06-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Propranolol Impurity 16.

CATO supplies Propranolol Impurity 16 (CAS 5234-06-0), a pharmacopoeial impurity reference standard (molecular formula C13H12O2, MW 200.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C13H12O2, Propranolol Impurity 16 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.23 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).

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.
