Description

Dimethyl POPOP is a high-purity organic scintillator compound, widely recognized for its excellent fluorescence properties. Its primary value lies in its ability to efficiently convert high-energy radiation into detectable light, making it a critical component in sensitive detection systems. This product is essential for industries and research institutions involved in liquid scintillation counting, nuclear physics, and radiation monitoring.

Application

• Liquid Scintillation Counting (LSC): Acts as a primary or secondary fluor (wavelength shifter) in cocktails for detecting low-energy beta emitters like tritium (3H) and carbon-14 (14C).
• Radiation Detection and Measurement: Used in the formulation of plastic and liquid scintillators for neutron, gamma, and alpha particle detection in physics research and environmental monitoring.
• Nuclear Medicine and Biochemistry: Employed in research assays that utilize radioactive tracers, particularly in drug metabolism studies and receptor-binding assays.
• Quality Control in Radiopharmaceuticals: Facilitates the accurate quantification of radioactivity in pharmaceutical preparations.
• High-Energy Physics Research: Incorporated into detector materials for particle physics experiments due to its fast fluorescence decay time and high light yield.
