Description
CATO supplies 3-(3,4-Dichlorophenoxy)benzenesulfonylchloride (CAS 885950-84-5), a certified reference material (molecular formula C12H7Cl3O3S, MW 337.61 g/mol) for analytical method development and quality control.
The molecular framework of 3-(3,4-Dichlorophenoxy)benzenesulfonylchloride (C12H7Cl3O3S) 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 its high hydrophobicity (logP), 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.
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), 3-(3,4-Dichlorophenoxy)benzenesulfonylchloride 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.
