'''Lead picrate''' is an [organic](/source/Organic_compound) [picrate](/source/picrate) salt.<ref name="Agrawal">{{cite book | title = High Energy Materials: Propellants, Explosives and Pyrotechnics | author = Jai Prakash Agrawal | publisher = John Wiley & Sons | date = 2015}}</ref> It is a sensitive and highly [explosive](/source/explosive) compound that is typically found as a [hydrate](/source/hydrate).<ref name="Matsukakwa" /> Dry lead picrate is extremely dangerous and cannot be handled without explosive decomposition occurring.

== History ==
Lead picrate was first discovered in the early 1900s. It was investigated by numerous militaries during the [First World War](/source/World_War_I) as a potential primary explosive, most notably [Germany](/source/Germany) for using it in [blasting caps](/source/blasting_caps).<ref name="Matsukakwa" />

== Preparation ==
Numerous [lead](/source/lead) precursors can be used to create lead picrate. Two of the simplest examples of lead picrate synthesis are the addition of [lead(II) oxide](/source/lead(II)_oxide) or [lead carbonate](/source/lead_carbonate) with [picric acid](/source/picric_acid).<ref name="Matsukakwa" />
