General description

2,5-Diphenyloxazole (also known as PPO or p-phenylphenoxazole) is a fluorescent organic compound. It can be also used as an organic scintillator due to its high photoluminescence quantum yield and intriguing luminescent properties. It is widely used as a fluorescent probe or dye in analytical chemistry and biochemistry. [1]

Application

2,5-Diphenyloxazole (PPO) can be used in:
  • fluorography techniques for the detection of tritium, tritiated glycopeptides, and 35S labeled proteins. [2]
  • liquid scintillation cocktails as primary and secondary fluors. [3]

Spectral and time-resolved fluorescence properties as well as relative fluorescence quantum yields of carbodiimide derivatives of 2.5-diphenyloxazole (PPO) (prepared by H2S elimination from the corresponding thioureas), of some intermediates in the preparation, and of several other PPO derivatives were investigated
