Chemical Structure
Description
As a certified reference material (CRM), 2-(Phenylthio)ethane-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.
2-(Phenylthio)ethane-1-sulfonyl chloride (CAS 83594-06-3), molecular formula C8H9ClO2S2 and molecular weight 236.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Phenylthio)ethane-1-sulfonyl chloride (C8H9ClO2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
