Chemical Structure

1-Methyl-1H-imidazole-5-carbonyl chloride CAS 41716-12-5 chemical structure

Description

As a certified reference material (CRM), 1-Methyl-1H-imidazole-5-carbonyl chloride 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.

1-Methyl-1H-imidazole-5-carbonyl chloride (CAS 41716-12-5) is a high-purity analytical reference standard with the molecular formula C5H5ClN2O and a molecular weight of 144.56 g/mol.

Based on its molecular formula C5H5ClN2O, 1-Methyl-1H-imidazole-5-carbonyl chloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 144.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
