Dinaphtho[2,3-d:2′,3′-f][1,3,2]dioxaphosphepin, 5,9-bis[2-(cyclohexyloxy)-1-naphthalenyl]-7-hydroxy-, 7-oxide (CAS 2168567-88-0), molecular formula C52H45O6P and molecular weight 796.88 g/mol, is a CATO reference standard with documented purity and traceability.
Dinaphtho[2,3-d:2′,3′-f][1,3,2]dioxaphosphepin, 5,9-bis[2-(cyclohexyloxy)-1-naphthalenyl]-7-hydroxy-, 7-oxide (C52H45O6P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
