Trinitrophenol (Picric acid)

Trinitrophenol, commonly known as picric acid, is a chemical compound historically used as an explosive and dye. It contains a benzene ring with three nitro groups and a hydroxyl group attached, making it highly reactive. Picric acid is sensitive to heat and shock, which can cause it to detonate violently. Besides its explosive properties, it was used as a yellow dye in textiles and paper. Today, its use is limited due to toxicity and explosive risks, though it still has applications in chemical synthesis and as a reference substance in laboratories.
