Description General description 1-Bromopyrene, a polycyclic aromatic hydrocarbon (PAH), is a mono bromo substituted pyrene derivative. Its synthesis has been reported. Its gas phase UV-absorption spectra in the UV wavelength range at elevated temperature has been studied. Electron affinitiy (EA) of 1-bromopyrene has been investigated using electron attachment desorption chemical ionization mass spectrometry (DCI-MS) and triple quadrupole tandem mass spectrometry. It participates in the synthesis of novel ruthenium (II) bipyridine or terpyridine complexes bearing pyrene moiety. The reaction of 1-bromopyrene cation radical with water in acetonitrile has been analyzed using the electron transfer stopped-flow (ETSF) method. Application 1-Bromopyrene is suitable reagent used in the comparative study of effect of substituents of some pyrene derivatives in inducing phototoxicity, DNA damage and repair in human skin keratinocytes and light-induced lipid peroxidation in methanol. It is suitable reagent used in the study to investigate the UV photon-assisted thermal decomposition of PAHs at elevated temperature. 1-Bromopyrene may be used as a standard to compare its spectral properties with that of pyrene based fluorescence probe. It may be used to study the effects of the addition of halogen hetero-atoms on the vapor pressures and thermodynamics of polycyclic aromatic hydrocarbons. It may be used in the synthesis of the following: • 2-methyl-4-pyren-1-yl-but-3-yn-2-ol • 1-ethynylpyrene • silsesquioxane (SSQ) based hybrid • ruthenium nanoparticles functionalized with pyrene moiety • mono- and di-pyrenyl perfluoroalkanes • oligo(1-bromopyrene)(OBrP) films • dinitropyrene-derived DNA adduct Packaging 1 g in glass bottle
