Isotope labelled 9-Bromophenanthrene (B687200), a halogenated polycyclic aromatic hydrocarbon that has been seen to have a room temperature phosphorescence that can be induced by β-cyclodextrin (β-CD) in the presence of cyclohexane; however, trace Fe(III) causes a decrease of the RTP emission. Molecular Formula: C14D9Br Solubility: Chloroform (Slightly), Methanol (Slightly, Heated) Molecular Weight: 266.18
