Chemical Structure

1,2,4,5-Tetramethylimidazole CAS 1739-83-9 chemical structure

Description

1,2,4,5-Tetramethylimidazole (CAS 1739-83-9) is a high-purity analytical reference standard with the molecular formula C7H12N2 and a molecular weight of 124.18 g/mol.

Owing to a nitrile group, 1,2,4,5-Tetramethylimidazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1,2,4,5-Tetramethylimidazole 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.
