3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carboxylic acid CAS 372107-36-3

Description

The occurrence of 3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carboxylic acid (CAS 372107-36-3), molecular formula C17H14N2O3 and molecular weight 294.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.30 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.

As a certified reference material (CRM), 3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
