1,5-Diphenyl-4,5-dihydro-1H-pyrazole CAS 2515-61-9

Description

The occurrence of 1,5-Diphenyl-4,5-dihydro-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,5-Diphenyl-4,5-dihydro-1H-pyrazole (CAS 2515-61-9), a certified reference material (molecular formula C15H14N2, MW 222.29 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,5-Diphenyl-4,5-dihydro-1H-pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.29 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.
