Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.52 g/mol gives 1,1,1-trifluoro-Methanesulfinyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,1,1-trifluoro-Methanesulfinyl chloride (CAS 20621-29-8), a certified reference material (molecular formula CClF3OS, MW 152.52 g/mol) for analytical method development and quality control.
1,1,1-trifluoro-Methanesulfinyl chloride (CClF3OS) contains sulfur-containing functionality, a hydroxyl group, fluorine/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.
As a certified reference material (CRM), 1,1,1-trifluoro-Methanesulfinyl 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.
