Chemical Structure

Benidipine Impurity 59 CAS 61311-83-9 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 Benidipine Impurity 59.

As a process- or degradation-related impurity, Benidipine Impurity 59 (CAS 61311-83-9, C23H22N2O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Benidipine Impurity 59 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
