Chemical Structure
Description
The molecular framework of (1-Cyclopropyl-1h-imidazol-2-yl)methanesulfonyl chloride (C7H9ClN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(1-Cyclopropyl-1h-imidazol-2-yl)methanesulfonyl chloride (CAS 1420801-75-7), molecular formula C7H9ClN2O2S and molecular weight 220.68 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (1-Cyclopropyl-1h-imidazol-2-yl)methanesulfonyl 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.
