Deuterated Compounds

Applications 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.

Applications Labelled 2,3-Butanedione (B690030). 2,3-Butanedione (Diacetyl), the molecule implicated in the disease known as popcorn lung, has now been implicated in amyloid-β peptide toxicity associated with Alzheimer’s disease. Diacetyl accelerates amyloid-β aggregation-a hallmark of Alzheimer’s disease. These preliminary finding raise the possibility of long-term neurological toxicity mediated by DA.
