2,4,6-Trinitrophenylmethylnitramine or tetryl (C₇H₅N₅O₈) is an explosive compound used to make detonators and explosive booster charges.

Tetryl is a nitramine booster explosive, though its use has been largely superseded by RDX. Tetryl is a sensitive secondary high explosive used as a booster, a small charge placed next to the detonator in order to propagate detonation into the main explosive charge.
