Dissolve in water. The solubility is about 1%.
Don't neutralize the acidity (especially with
ammonia) because that could generate more sensitive
explosive picrate salts. The danger of explosion
exists only with dry material. Keep everything
wet and you'll be OK.

Look in the archives at and
you'll find plenty of earlier Histonet corresponence
about picric acid, and references to published
infornmation that you can check for yourself.
