1-[(3-bromophenyl)methyl]-3,5-dimethyl-1H-pyrazole-4-carboxylic acid CAS 1153371-57-3

Description

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.

1-[(3-bromophenyl)methyl]-3,5-dimethyl-1H-pyrazole-4-carboxylic acid (CAS 1153371-57-3) is a high-purity analytical reference standard with the molecular formula C13H13BrN2O2 and a molecular weight of 309.16 g/mol.

Structurally, 1-[(3-bromophenyl)methyl]-3,5-dimethyl-1H-pyrazole-4-carboxylic acid (C13H13BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 309.16 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
