Chemical Structure
Description
The molecular framework of (4-Bromo-3-(4-bromophenyl)-1H-pyrazol-5-yl)methanol (C10H12Br2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(4-Bromo-3-(4-bromophenyl)-1H-pyrazol-5-yl)methanol (CAS 1239460-39-9) is a high-purity analytical reference standard with the molecular formula C10H12Br2N2O and a molecular weight of 336.02 g/mol.
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.
