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