Chemical Structure
Description
As a certified reference material (CRM), 1-Methyl-1H-imidazole-2-carbonyl chloride hydrochloride 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.
CATO supplies 1-Methyl-1H-imidazole-2-carbonyl chloride hydrochloride (CAS 2073066-52-9), a certified reference material (molecular formula C5H5ClN2OHCl, MW 181.02 g/mol) for analytical method development and quality control.
1-Methyl-1H-imidazole-2-carbonyl chloride hydrochloride (C5H5ClN2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
