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 2-(3-Chloro-4-fluorophenyl)-1,2-benzisothiazol-3(2H)-one (CAS 565166-89-4), a certified reference material (molecular formula C13H7ClFNOS, MW 279.72 g/mol) for analytical method development and quality control.
2-(3-Chloro-4-fluorophenyl)-1,2-benzisothiazol-3(2H)-one (C13H7ClFNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-(3-Chloro-4-fluorophenyl)-1,2-benzisothiazol-3(2H)-one 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.
