CATO supplies 4-Methoxybenzenesulfonyl chloride 98-68-0 Benzenesulfonyl chloride, 4-methoxy- Benzenesulfonyl chloride, p-methoxy- NSC-403292 NSC403292 p-Anisylsulfonyl chloride p-Methoxybenzenesulfonyl chloride p-Methoxyphenylsulfonyl chloride (CAS 98-68-0), a certified reference material (molecular formula C7H13ClO3S, MW 212.69 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methoxybenzenesulfonyl chloride 98-68-0 Benzenesulfonyl chloride, 4-methoxy- Benzenesulfonyl chloride, p-methoxy- NSC-403292 NSC403292 p-Anisylsulfonyl chloride p-Methoxybenzenesulfonyl chloride p-Methoxyphenylsulfonyl chloride (C7H13ClO3S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
