Chemical Structure

N-(4-(1-Phenyl-1H-pyrazol-5-yl)phenyl)nicotinamide CAS 62089-21-8 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 N-(4-(1-Phenyl-1H-pyrazol-5-yl)phenyl)nicotinamide.

N-(4-(1-Phenyl-1H-pyrazol-5-yl)phenyl)nicotinamide (CAS 62089-21-8) is a high-purity analytical reference standard with the molecular formula C21H16N4O and a molecular weight of 340.38 g/mol.

The molecular framework of N-(4-(1-Phenyl-1H-pyrazol-5-yl)phenyl)nicotinamide (C21H16N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
