Chemical Structure

Verapamil Impurity 26 CAS 78-89-7 chemical structure

Description

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.

CATO supplies Verapamil Impurity 26 (CAS 78-89-7), a pharmacopoeial impurity reference standard (molecular formula C3H7ClO, MW 94.54 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, Verapamil Impurity 26 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 94.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
