Chemical Structure
Description
The occurrence of 5-Chloro-2-thiobenzenesulfonyl fluoride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-2-thiobenzenesulfonyl fluoride (CAS 108158-05-0), a certified reference material (molecular formula C4H2ClFO2S2, MW 200.64 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H2ClFO2S2, 5-Chloro-2-thiobenzenesulfonyl fluoride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.64 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Chloro-2-thiobenzenesulfonyl fluoride 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.
