Acetone Peroxide

Acetone peroxide (triacetone triperoxide, peroxyacetone, TATP, TCAP) is an organic peroxide and a primary high explosive. It takes the form of a white crystalline powder with a distinctive bleach-like odor.

It is susceptible to heat, friction, and shock. The instability is greatly altered by impurities, including its own oligomers. It is not easily soluble in water. It is more stable and less sensitive when wet.
