Description and Uses

PPO can be used as a dopant that improves the photo-electric feedback of plastic scintillators which are used as radiation detectors for nuclear materials. It can be coated on peptide substrates to facilitate radioactive labelling which can enable determination of substrate specificity of lysine methyltransferase enzymes. It may also be used in the fabrication of organic luminescent materials which can be used in light emitting diodes (LEDs).
