DADP (Diacetone Diperoxide)
Definition
A six-membered ring peroxide co-product of TATP synthesis. Less stable than TATP. Detected alongside TATP in post-blast samples where the synthesis conditions favoured partial DADP formation. LC-MS/MS: [M+NH4]+ at m/z 166.

Common questions
Why does finding DADP alongside TATP in a post-blast sample matter to investigators?+
The ratio of DADP to TATP in a sample can reflect the specific reaction conditions used, such as acid concentration or temperature, during synthesis, which sometimes helps link recovered residue to a particular batch or method and supports source attribution beyond a simple TATP identification.
Why is DADP's lower stability relevant to sample handling in the lab?+
Because DADP degrades more readily than TATP, its concentration in a recovered residue can drop between collection and analysis, so a sample that shows only TATP is not proof that DADP was never present; timing and storage conditions can account for its absence.
