Chemical Structure
Description
rel-(2R,2'R,3R,3'R)-3,3'-di-tert-Butyl-4,4'-diphenyl-2,2',3,3'-tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole (CAS 2301856-53-9) is a high-purity analytical reference standard with the molecular formula C34H36O2P2 and a molecular weight of 538.60 g/mol.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, rel-(2R,2'R,3R,3'R)-3,3'-di-tert-Butyl-4,4'-diphenyl-2,2',3,3'-tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
