Chemical Structure
Description
The occurrence of Dichloromethanesulfinyl chloride is closely related to sulfur-containing functionality, a hydroxyl group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Dichloromethanesulfinyl chloride (CAS 62479-74-7), a certified reference material (molecular formula CHCl3OS, MW 167.44 g/mol) for analytical method development and quality control.
Dichloromethanesulfinyl chloride (CHCl3OS) contains sulfur-containing functionality, a hydroxyl group, chlorine substitution. Halogen substitution raises its density and boiling point; 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 Dichloromethanesulfinyl 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.
