Thermal Stability
Organic peroxides are thermally unstable substances which may undergo self-accelerating decomposition. The Self Accelerating Decomposition Temperature (SADT) is the lowest temperature at which self-accelerating decomposition may occur.
Recommended Storage
Note: When stored according to these recommended conditions, Tert-Butyl hydroperoxide will remain within specifications for a period of at least 3 months after delivery.
