Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(1R,2S)-2-Methoxycyclopentanesulfonyl Chloride (CAS 1864003-13-3) is a high-purity analytical reference standard with the molecular formula C6H11ClO3S and a molecular weight of 198.67 g/mol.
The molecular framework of (1R,2S)-2-Methoxycyclopentanesulfonyl Chloride (C6H11ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (1R,2S)-2-Methoxycyclopentanesulfonyl Chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
