self-reactive substance
Technical term in chemistry for a substance that can undergo a strongly exothermic decomposition even without oxygen, often subject to transport and storage regulations.
Self-reactive substances are classified as Class 4.1 under the UN dangerous goods transport regulations.
Because this compound is a self-reactive substance, its storage temperature must be strictly controlled.
Similar concept but often used in a broader sense for substances that decompose spontaneously; 自己反応性物質 specifically emphasizes the exothermic reaction hazard.
Compound of 自己 (self), 反応性 (reactivity), and 物質 (substance). A modern technical term coined in the field of chemistry.
