Chemical Structure
Description
(ethenesulfonyl)cyclopentane (CAS 1341708-17-5), molecular formula C7H12O2S and molecular weight 160.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (ethenesulfonyl)cyclopentane (C7H12O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
