Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Cyclopentyl methanesulfonate (CAS 16156-57-3), molecular formula CH4O3SC5H10O and molecular weight 182.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Cyclopentyl methanesulfonate (CH4O3SC5H10O) 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.
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.
