Trinitrophloroglucinol (TNPG) or 2,4,6-trinitro-1,3,5-benzenetriol is a nitrated aromatic phenol, used as high explosive. It has the chemical formula C6H3N3O9.
Addition of trinitrophloroglucinol to an aq. solution of ferric chloride gives a blue-violet product.
Potassium bicarbonate mixed with TNPG gives its tripotassium salt.
Trinitrophloroglucinol is a yellowish or yellow-orange solid. It is soluble in water and organic solvents.
There is little available data about TNGU's explosive properties. Some sources indicate that it's somewhat sensitive.
Potassium salts of TNPG have been found to be more stable than its parent compound.
TNPG is not available to the public and when available it's more expensive than similar explosive compounds.
- Make blasting caps
- Make colored compounds
Trinitrophloroglucinol is toxic and a powerful explosive. Handle it with care.
In closed containers.
Should be carefully incinerated or neutralized with an oxidizing solution.
