Description
CATO supplies (11aS)-3,7-Bis(4-chlorophenyl)-10,11,12,13-tetrahydro-5-hydroxy-diindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocin (CAS 1258327-05-7), a certified reference material (molecular formula C29H21Cl2O4P, MW 535.35 g/mol) for analytical method development and quality control.
(11aS)-3,7-Bis(4-chlorophenyl)-10,11,12,13-tetrahydro-5-hydroxy-diindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocin (C29H21Cl2O4P) contains a steroid core, a phosphate ester group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
