pikriinihappoa

Pikriinihappoa, also known as picric acid, is a yellow crystalline solid with the chemical formula C6H3N3O7. It is a highly explosive compound and is also known for its acidic properties, despite its name. It is technically a strong organic acid, more acidic than many inorganic acids. Pikriinihappoa is synthesized by nitrating phenol, a process that introduces nitro groups onto the aromatic ring. Historically, it has been used as a dye, a laboratory reagent, and in some explosives. Its explosive nature stems from the presence of multiple nitro groups, which can rapidly decompose and release a large amount of energy.

Due to its instability and hazardous nature, the use of pikriinihappoa has declined significantly. It is now primarily encountered in historical contexts or in specialized laboratory applications where strict safety protocols can be observed. When stored, it can form sensitive picrates with metals, increasing its shock sensitivity. For this reason, it is often stored wetted with water to reduce its explosive potential. Handling pikriinihappoa requires extreme caution and specialized training. Its strong acidic nature also means it can cause severe burns on contact with skin and is toxic if ingested.
