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 Ethyl 2-{3-[(4-chlorophenyl)methyl]-4-oxo-3,4-dihydrophthalazin-1-yl}acetate (CAS 866151-32-8), a certified reference material (molecular formula C19H17ClN2O3, MW 356.80 g/mol) for analytical method development and quality control.
Ethyl 2-{3-[(4-chlorophenyl)methyl]-4-oxo-3,4-dihydrophthalazin-1-yl}acetate (C19H17ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 Ethyl 2-{3-[(4-chlorophenyl)methyl]-4-oxo-3,4-dihydrophthalazin-1-yl}acetate 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.
