1,2-Dichloroethane-1-sulfonyl chloride CAS 84501-81-5

Description

1,2-Dichloroethane-1-sulfonyl chloride (CAS 84501-81-5), molecular formula C2H3Cl3O2S and molecular weight 197.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2-Dichloroethane-1-sulfonyl chloride (C2H3Cl3O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), 1,2-Dichloroethane-1-sulfonyl 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.
