(11bR)-4-Hydroxy-2,6-bis(5'-phenyl-[1,1':3',1''-terphenyl]-4'-yl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide CAS 2640982-29-0

Description

CATO supplies (11bR)-4-Hydroxy-2,6-bis(5'-phenyl-[1,1':3',1''-terphenyl]-4'-yl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (CAS 2640982-29-0), a certified reference material (molecular formula C68H45O4P, MW 957.06 g/mol) for analytical method development and quality control.

(11bR)-4-Hydroxy-2,6-bis(5'-phenyl-[1,1':3',1''-terphenyl]-4'-yl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (C68H45O4P) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
