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-2-oxo-2,3-dihydro-1H-indol-4-yl)ethyl 4-(trifluoromethyl)benzoate (CAS 303188-00-3), a certified reference material (molecular formula C18H13ClF3NO3, MW 383.75 g/mol) for analytical method development and quality control.
2-(3-chloro-2-oxo-2,3-dihydro-1H-indol-4-yl)ethyl 4-(trifluoromethyl)benzoate (C18H13ClF3NO3) contains a steroid core, an amide group, 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, the carboxyl group imparts weak acidity; 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-2-oxo-2,3-dihydro-1H-indol-4-yl)ethyl 4-(trifluoromethyl)benzoate 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.
