Picric acid, also known as 2,4,6-trinitrophenol, is a pale yellow crystalline solid with a bitter taste and a high degree of chemical reactivity. Historically used in dyes, explosives, and as a reagent in laboratory analysis, it is noted for its strong nitrating properties. Picric acid is both flammable and toxic, requiring careful handling and storage under specific conditions to prevent accidental detonation or degradation. Its role in historical and industrial contexts highlights its versatility, though its use has diminished due to safety concerns and the development of alternative materials.

FAQs
Picric acid is primarily used in explosives, dye manufacturing, and as a reagent in laboratories. In explosives, it has historically been utilised as a component in munitions and detonators. In the textile industry, it serves as a dyeing agent for silk and wool. Additionally, it plays a role in chemical analysis and histology, where it is used as a staining agent and fixative.

Picric acid presents several hazards beyond its toxicity. It is flammable and can become highly explosive when dry, particularly in the presence of heat, friction, or shock. It forms unstable salts when in contact with metals, concrete, or alkaline substances, which are highly sensitive to impact or heat. Additionally, it can produce toxic gases like carbon monoxide and nitrogen oxides during combustion. Improper handling or storage, such as allowing the acid to dry out, increases the risk of explosions. Always store Picric Acid wetted with at least 40% water and follow strict handling protocols to minimise risks.
