The occurrence of 3-((4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)methyl)benzoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-((4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)methyl)benzoic acid (CAS 175203-24-4) is a high-purity analytical reference standard with the molecular formula C13H13BrN2O2 and a molecular weight of 309.16 g/mol.
The molecular framework of 3-((4-Bromo-3,5-dimethyl-1h-pyrazol-1-yl)methyl)benzoic acid (C13H13BrN2O2) 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.
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.
