Chemical Structure
Description
The occurrence of Benidipine Impurity 57 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Benidipine Impurity 57 (CAS 49840-66-6), a pharmacopoeial impurity reference standard (molecular formula C9H18N2, MW 154.25 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Benidipine Impurity 57 (C9H18N2) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
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.
