Chemical Structure
Description
The occurrence of Cyclopent-3-en-1-yl methanesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Cyclopent-3-en-1-yl methanesulfonate (CAS 253680-54-5), molecular formula CH4O3SC5H8O and molecular weight 180.22 g/mol, is a CATO reference standard with documented purity and traceability.
Cyclopent-3-en-1-yl methanesulfonate (CH4O3SC5H8O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), Cyclopent-3-en-1-yl methanesulfonate 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.
