Picric acid

Description:
Picric acid, also known as 2,4,6-trinitrophenol, is a yellow crystalline solid with the chemical formula C6H3N3O7. It is notable for its strong acidic properties, being a weak acid with a pKa around 0.38. Picric acid is highly soluble in water, alcohol, and ether, which contributes to its versatility in various applications. Historically, it has been used as a dye, a precursor in the synthesis of explosives, and in the field of medicine as an antiseptic. However, it is important to note that picric acid is also classified as a hazardous material due to its explosive potential when dry and its toxic effects upon exposure. It can cause severe skin and eye irritation, and its handling requires strict safety protocols. In addition to its chemical properties, picric acid can form stable salts with metals, known as picrates, which are also of interest in both industrial and research contexts. Overall, picric acid is a compound of significant historical and practical importance, but it must be managed with caution due to its hazardous nature.
