Chemical Structure
Description
Owing to organophosphorus functionality, bromine substitution, a polycyclic aromatic system, Cyclohexyltriphenylphosphonium Bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 425.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
