For engineers and scientists designing and implementing advanced detection systems, a deep understanding of the materials employed is essential. 2,5-Diphenyloxazole (PPO, CAS 92-71-7) stands out as a critical organic scintillator, widely used for its exceptional optical and electronic properties. This article offers technical insights into PPO, covering its key specifications and its application in cutting-edge detection technologies. As a premier manufacturer and supplier in China, we provide PPO that meets the rigorous demands of scientific instrumentation.

At its core, PPO is an organic scintillator known for its ability to convert ionizing radiation into light. Its molecular structure, featuring conjugated phenyl rings on an oxazole core, facilitates efficient energy absorption and emission. The characteristic properties that make PPO invaluable include its high fluorescence quantum yield, fast decay time (approximately 1 ns), and emission spectrum peaking at 385 nm. These attributes are crucial for applications requiring precise timing resolution and high signal-to-noise ratios, such as in particle physics experiments or high-sensitivity radiation monitoring.

For procurement managers and R&D teams, understanding the technical specifications of PPO is key to selecting the right grade for their application. The melting point, typically between 72-74 °C, is a reliable indicator of purity. Higher purity generally correlates with better scintillation performance, as impurities can lead to luminescence quenching and reduced light output. We ensure our PPO (CAS 92-71-7) adheres to stringent purity standards, making it suitable for demanding scientific instrumentation. When you buy PPO from us, you invest in guaranteed quality.

PPO's primary application is as a wavelength shifter in both liquid and plastic scintillators. In liquid scintillation cocktails, it efficiently absorbs UV photons generated by solvent excitation or from secondary scintillators, re-emitting them at a longer wavelength that is more readily detected by photomultiplier tubes (PMTs). This spectral matching is vital for maximizing the overall efficiency of the detection system. Its role as a primary scintillator also means it is directly excited by radiation, making its intrinsic properties paramount.

When considering sourcing PPO, selecting a reliable supplier from China offers significant advantages in terms of cost-effectiveness and consistent supply.
