Chemical Structure
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.
2-(4-Isopropylphenyl)-1H-benzo[d]imidazole (CAS 67273-56-7) is a high-purity analytical reference standard with the molecular formula C16H16N2 and a molecular weight of 236.31 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(4-Isopropylphenyl)-1H-benzo[d]imidazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
