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-((2,5-Dimethoxyphenyl)amino)benzo[d]isothiazole 1,1-dioxide (CAS 303066-48-0), a certified reference material (molecular formula C15H14N2O4S, MW 318.35 g/mol) for analytical method development and quality control.
The molecular framework of 3-((2,5-Dimethoxyphenyl)amino)benzo[d]isothiazole 1,1-dioxide (C15H14N2O4S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3-((2,5-Dimethoxyphenyl)amino)benzo[d]isothiazole 1,1-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
