2,5-Diphenyloxazole (PPO) is an organic scintillator. It is used as a wavelength shifter (also called a "primary shifter" or "fluor"), which means that it converts shorter wavelength light to longer wavelength light. Its output spectrum peaks at 385 nm, which is in the range of UV light.
P 2565 (OTTO) 2,5-Diphenyloxazole, (PPO) scintillation grade, 99%+ Cas 92-71-7 - 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. P 2565 (OTTO) 2,5-Diphenyloxazole, (PPO) scintillation grade, 99%+ Cas 92-71-7 - used in the fabrication of organic luminescent materials which can be used in light emitting diodes (LEDs).
