Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2,5-Dichloro-N-[4-(3-chlorothiophen-2-yl)-1,3-thiazol-2-yl]benzene-1-sulfonamide (CAS 376348-99-1), a certified reference material (molecular formula C13H7Cl3N2O2S3, MW 425.76 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Dichloro-N-[4-(3-chlorothiophen-2-yl)-1,3-thiazol-2-yl]benzene-1-sulfonamide (C13H7Cl3N2O2S3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
