Chemical Structure
Description
As a certified reference material (CRM), 5-Chloro-n-cyclopentyl-1-methyl-1h-imidazole-4-sulfonamide 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 5-Chloro-n-cyclopentyl-1-methyl-1h-imidazole-4-sulfonamide (CAS 1154914-95-0), a certified reference material (molecular formula C9H14ClN3O2S, MW 263.74 g/mol) for analytical method development and quality control.
5-Chloro-n-cyclopentyl-1-methyl-1h-imidazole-4-sulfonamide (C9H14ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
