Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 130.53 g/mol gives 1H-Imidazole-4-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1H-Imidazole-4-carbonyl chloride (CAS 56460-32-3), a certified reference material (molecular formula C4H3ClN2O, MW 130.53 g/mol) for analytical method development and quality control.
1H-Imidazole-4-carbonyl chloride (C4H3ClN2O) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1H-Imidazole-4-carbonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
