Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n-Phenyl-3-[3-(phenylsulfamoyl)benzenesulfonyl]benzene-1-sulfonamide (CAS 300405-44-1), molecular formula C24H20N2O6S3 and molecular weight 528.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n-Phenyl-3-[3-(phenylsulfamoyl)benzenesulfonyl]benzene-1-sulfonamide (C24H20N2O6S3) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 n-Phenyl-3-[3-(phenylsulfamoyl)benzenesulfonyl]benzene-1-sulfonamide 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.
