Chemical Structure

1-Butyl-2-methyl-1H-benzo[d]imidazole CAS 4887-85-8 chemical structure

Description

1-Butyl-2-methyl-1H-benzo[d]imidazole (CAS 4887-85-8) is a high-purity analytical reference standard with the molecular formula C12H16N2 and a molecular weight of 188.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Butyl-2-methyl-1H-benzo[d]imidazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.27 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.

As a certified reference material (CRM), 1-Butyl-2-methyl-1H-benzo[d]imidazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
