Chemical Structure

1-Benzyl-1H-pyrazol-4-ol CAS 226989-35-1 chemical structure

Description

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.

CATO supplies 1-Benzyl-1H-pyrazol-4-ol (CAS 226989-35-1), a certified reference material (molecular formula C10H10N2O, MW 174.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H10N2O, 1-Benzyl-1H-pyrazol-4-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 174.20 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.

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.
