Tetryl

Tetryl, or trinitrophenylmethylnitramine, has various common names such as nitramine, tetralite, and tetril. It is fairly sensitive and it can be initiated from flame, friction, shock, or sparks. Tetryl is commonly used as a booster explosive where stable explosives need more than simply an initiator to cause them to detonate. It is no longer manufactured in the United States and it is an environmental hazard.
