Description
As a certified reference material (CRM), 2-Methoxy-2-(oxan-3-yl)ethane-1-sulfonyl 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.
2-Methoxy-2-(oxan-3-yl)ethane-1-sulfonyl chloride (CAS 1781380-26-4) is a high-purity analytical reference standard with the molecular formula C8H15ClO4S and a molecular weight of 242.72 g/mol.
The molecular framework of 2-Methoxy-2-(oxan-3-yl)ethane-1-sulfonyl chloride (C8H15ClO4S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
