Chemical Structure

1-Cyclohexyl-2-phenyl-1H-benzo[d]imidazole-5-carboxylic acid CAS 390815-08-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 320.39 g/mol gives 1-Cyclohexyl-2-phenyl-1H-benzo[d]imidazole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Cyclohexyl-2-phenyl-1H-benzo[d]imidazole-5-carboxylic acid (CAS 390815-08-4), a certified reference material (molecular formula C20H20N2O2, MW 320.39 g/mol) for analytical method development and quality control.

1-Cyclohexyl-2-phenyl-1H-benzo[d]imidazole-5-carboxylic acid (C20H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
