Description
CATO supplies Nicardipine Cyclohexenone Impurity (CAS 87625-92-1), a pharmacopoeial impurity reference standard (molecular formula C15H15NO5, MW 289.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C15H15NO5, Nicardipine Cyclohexenone Impurity 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 289.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
