421-83-0 Trifluoromethanesulfonyl chloride trifluoro-methanesulfonyl chloride trifluoromethanesulphonyl chloride trifluoromethylsulphonyl chloride CAS 421-83-0

Description

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 supplies 421-83-0 Trifluoromethanesulfonyl chloride trifluoro-methanesulfonyl chloride trifluoromethanesulphonyl chloride trifluoromethylsulphonyl chloride (CAS 421-83-0), a certified reference material (molecular formula CClF3O2S, MW 168.52 g/mol) for analytical method development and quality control.

The molecular framework of 421-83-0 Trifluoromethanesulfonyl chloride trifluoro-methanesulfonyl chloride trifluoromethanesulphonyl chloride trifluoromethylsulphonyl chloride (CClF3O2S) is characterized by a sulfone group, fluorine/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.

As a certified reference material (CRM), 421-83-0 Trifluoromethanesulfonyl chloride trifluoro-methanesulfonyl chloride trifluoromethanesulphonyl chloride trifluoromethylsulphonyl 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.
