A yellow acid dye that was prepared in 1771 by Woulfe by treating [[indigo\|indigo]] with [[nitric%20acid\|nitric acid]]. Picric acid had early use as a textile dye for [[wool\|wool]] and [[silk\|silk]]. It was quickly learned that picric acid had poor washfastness and was explosive. As a textile colorant, it was replaced by naphthol dyes by the late 1800s. However, it was still used as an explosive until it was replaced by the less powerful, but safer, trinitrotoluene (TNT) in 1902.
