Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,4-Dichloro-n-methoxy-n-methylbenzenesulfonamide (CAS 923679-89-4), a certified reference material (molecular formula C8H9Cl2NO3S, MW 270.13 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dichloro-n-methoxy-n-methylbenzenesulfonamide (C8H9Cl2NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 3,4-Dichloro-n-methoxy-n-methylbenzenesulfonamide 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.
