Chemical Structure
Description
The occurrence of 5-Propyl-1H-imidazole-4-carbonyl chloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Propyl-1H-imidazole-4-carbonyl chloride (CAS 459432-76-9), a certified reference material (molecular formula C7H9ClN2O, MW 172.61 g/mol) for analytical method development and quality control.
5-Propyl-1H-imidazole-4-carbonyl chloride (C7H9ClN2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Propyl-1H-imidazole-4-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.
