2,4,6-Trinitroaniline, C6H4N4O6, abbreviated as TNA and also known as picramide, a nitrated amine. The appearance of trinitroaniline varies from yellow to orange to red depending on its purity and concentration.

Applications

Trinitroaniline is only used in modern times in the small warheads of some explosive devices such as mortars. In World War II it was used by Imperial Japanese Navy as Type 97 bakuyaku (Model 1931 explosive) in some versions of gun projectiles instead of less stable burster schimose (picric acid).[2] It was also used in the Yokosuka MXY-7 Ohka, a kamikaze antishipping human-guided rocket aircraft.

Health and safety

Trinitroaniline is dangerously explosive and also hepatoxic.[3] Symptoms of exposure to this compound may include skin and eye irritation, headache, drowsiness, weakness, cyanosis, and respiratory distress.
