Chemical Structure
Description
The occurrence of 2-Methoxy-2-(oxan-4-yl)ethane-1-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methoxy-2-(oxan-4-yl)ethane-1-sulfonyl chloride (CAS 1890073-41-2), molecular formula C8H15ClO4S and molecular weight 242.72 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methoxy-2-(oxan-4-yl)ethane-1-sulfonyl chloride (C8H15ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-Methoxy-2-(oxan-4-yl)ethane-1-sulfonyl 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.
