Description
CATO manufactures 1,3-dioxan-5-ylmethanesulfonyl 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.
1,3-dioxan-5-ylmethanesulfonyl chloride (CAS 1989671-23-9) is a high-purity analytical reference standard with the molecular formula C5H9ClO4S and a molecular weight of 200.64 g/mol.
Owing to a carbohydrate-derived structure, a sulfone group, chlorine substitution, 1,3-dioxan-5-ylmethanesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
