Chemical Structure

(1,3-Diphenyl-1h-pyrazol-4-yl)methanol CAS 40278-32-8 chemical structure

Description

(1,3-Diphenyl-1h-pyrazol-4-yl)methanol (CAS 40278-32-8) is a high-purity analytical reference standard with the molecular formula C16H14N2O and a molecular weight of 250.30 g/mol.

The molecular framework of (1,3-Diphenyl-1h-pyrazol-4-yl)methanol (C16H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
