Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

(11bR)-4-Hydroxy-2,6-diphenyl-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (CAS 791616-65-4), molecular formula C32H29O4P and molecular weight 508.54 g/mol, is a CATO reference standard with documented purity and traceability.

(11bR)-4-Hydroxy-2,6-diphenyl-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (C32H29O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 (11bR)-4-Hydroxy-2,6-diphenyl-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide 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.
