Chemical Structure

5-Ethynyl-4-methyl-1H-imidazole CAS 2228337-84-4 chemical structure

Description

5-Ethynyl-4-methyl-1H-imidazole (CAS 2228337-84-4), molecular formula C6H6N2 and molecular weight 106.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, an aromatic ring system, 5-Ethynyl-4-methyl-1H-imidazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 106.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-Ethynyl-4-methyl-1H-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.
