2-[3-(4-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]acetic acid CAS 905811-75-8

Description

CATO supplies 2-[3-(4-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]acetic acid (CAS 905811-75-8), a certified reference material (molecular formula C17H13N3O4, MW 323.30 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-[3-(4-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.30 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).

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.
