Chemical Structure

1-(3,4-Difluorophenyl)-1H-benzo[d]imidazole-5-carboxylic acid CAS 442531-67-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.22 g/mol gives 1-(3,4-Difluorophenyl)-1H-benzo[d]imidazole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(3,4-Difluorophenyl)-1H-benzo[d]imidazole-5-carboxylic acid (CAS 442531-67-1), a certified reference material (molecular formula C14H8F2N2O2, MW 274.22 g/mol) for analytical method development and quality control.

Structurally, 1-(3,4-Difluorophenyl)-1H-benzo[d]imidazole-5-carboxylic acid (C14H8F2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 274.22 g/mol, it falls into the medium-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.

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.
