Chemical Structure

Acebutolol Impurity 1 CAS CATO-C4X-15301 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 365.42 g/mol gives Acebutolol Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Acebutolol Impurity 1 (CAS CATO-C4X-15301), a pharmacopoeial impurity reference standard (molecular formula C18H27N3O5, MW 365.42 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H27N3O5, Acebutolol Impurity 1 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
