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 4-(4-Chlorophenyl)-7,7-dimethyl-4,6,7,8-tetrahydro-2H-chromene-2,5(3H)-dione (CAS 338750-76-8), a certified reference material (molecular formula C17H17ClO3, MW 304.77 g/mol) for analytical method development and quality control.
4-(4-Chlorophenyl)-7,7-dimethyl-4,6,7,8-tetrahydro-2H-chromene-2,5(3H)-dione (C17H17ClO3) contains a steroid core, a hydroxyl group, an ether linkage, 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 4-(4-Chlorophenyl)-7,7-dimethyl-4,6,7,8-tetrahydro-2H-chromene-2,5(3H)-dione 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.
