Application:	1,4-Bis(5-phenyl-2-oxazolyl) benzene or POPOP is widely used to detect radioactivity by scintillation counting.
Features and Benefits:	1,4-Bis(5-phenyl-2-oxazolyl) benzene or POPOP has the following advantages: • High fluorescence quantum yield. • High molar absorptivity. • Large Stokes Shift. • High Photostability in most organic solvents.
General description:	1,4-Bis(5-phenyl-2-oxazolyl) benzene, also known as POPOP, is a well-known scintillation luminophore. It is an efficient fluorescent organic compound with high stokes shift. The POPOP dye is photostable in polar protic and polar aprotic solvents. The resulting photochemical quantum yield and the photodecomposition rate depend on the solvent′s electron affinity.
Packaging:	5, 10, 25, 100 g in poly bottle
