2-chloro-1,1-dioxo-1$l^{6}-thiolane-2-sulfonyl chloride (CAS 1955547-79-1), molecular formula C4H6Cl2O4S2 and molecular weight 253.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-chloro-1,1-dioxo-1$l^{6}-thiolane-2-sulfonyl chloride (C4H6Cl2O4S2) is characterized by a carbohydrate-derived structure, a sulfone group, 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.
CATO manufactures 2-chloro-1,1-dioxo-1$l^{6}-thiolane-2-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.
