Description
CATO manufactures 2-(4-chlorophenyl)ethene-1-sulfonyl fluoride 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.
CATO supplies 2-(4-chlorophenyl)ethene-1-sulfonyl fluoride (CAS 1819971-28-2), a certified reference material (molecular formula C8H6ClFO2S, MW 220.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H6ClFO2S, 2-(4-chlorophenyl)ethene-1-sulfonyl fluoride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
