Description

(4-ethoxy-4-oxidanylidene-butyl)-triphenyl-phosphanium bromide (4-ethoxy-4-oxobutyl)-triphenylphosphonium bromide 50479-11-3 A828136 (CAS 50479-11-3), molecular formula C24H44O2PBr and molecular weight 475.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (4-ethoxy-4-oxidanylidene-butyl)-triphenyl-phosphanium bromide (4-ethoxy-4-oxobutyl)-triphenylphosphonium bromide 50479-11-3 A828136 (C24H44O2PBr) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 475.49 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
