1,3-Diphenyl-1H-pyrazole CAS 4492-01-7

Description

Compared with other compounds in its class, the molecular weight of 220.27 g/mol gives 1,3-Diphenyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,3-Diphenyl-1H-pyrazole (CAS 4492-01-7), a certified reference material (molecular formula C15H12N2, MW 220.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H12N2, 1,3-Diphenyl-1H-pyrazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
