(11bR)-4-Hydroxy-2,6-bis(2,3,4,5,6-pentamethylphenyl)-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 4-oxide (CAS 1221940-48-2), molecular formula C42H41O4P and molecular weight 640.75 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C42H41O4P, (11bR)-4-Hydroxy-2,6-bis(2,3,4,5,6-pentamethylphenyl)-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 4-oxide contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 640.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
