Tetryl

Tetryl (trinitrophenylmethylnitramine) is a bright-yellow crystalline substance, odorless, with a salty taste. Tetryl is non-hygroscopic and insoluble in water. It can be pressed relatively easily to a density of 1.60-1.65.

The sensitivity of tetryl to mechanical action is somewhat lower than that of PETN and RDX, but it may also detonate when struck by a rifle bullet.

Tetryl burns with an energetic blue flame without soot. Burning may transition to detonation. It does not chemically interact with metals. It is used for manufacturing booster detonators in various munitions and for loading certain types of detonator caps.
