Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-N-(2-((4-methyl-1,2,3-thiadiazol-5-yl)thio)ethyl)benzenesulfonamide (CAS 478063-53-5) is a high-purity analytical reference standard with the molecular formula C11H12ClN3O2S3 and a molecular weight of 349.88 g/mol.
The molecular framework of 4-Chloro-N-(2-((4-methyl-1,2,3-thiadiazol-5-yl)thio)ethyl)benzenesulfonamide (C11H12ClN3O2S3) 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 4-Chloro-N-(2-((4-methyl-1,2,3-thiadiazol-5-yl)thio)ethyl)benzenesulfonamide 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.
