Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1R,2R)-2-Methoxycyclopentanesulfonyl Chloride.
(1R,2R)-2-Methoxycyclopentanesulfonyl Chloride (CAS 1820581-26-7), molecular formula C6H11ClO3S and molecular weight 198.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R,2R)-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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (1R,2R)-2-Methoxycyclopentanesulfonyl 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.
