Use
Picric acid is a white to yellowish crystalline substance, soluble in most organic solvents and highly flammable. Picric acid is a derivative of phenol. It reacts with metals to form metal picrates, which like picric acid itself are highly sensitive. It is often used for tissue fixative (Bouin solution) for histology specimens, as a booster to detonate another, less sensitive explosive, such as trinitotoluene (TNT). It is used in the manufacture of fireworks, matches, electric batteries, coloured glass, dyes, antiseptics, explosives, disinfectants, leather industries, pharmaceutical, and textile. Picric acid is also used as a yellow dye, as an antiseptic, and in the synthesis of chloropicrin, or nitro-trichloromethane. Picric acids are highly sensitive to heat, shock, or friction and because of the explosive nature it is among the most hazardous substances found in the laboratory.
