Chemical Structure
Basic Info
2-Hydroxybenzoic Acid, also known as salicylic acid, is a common organic carboxylic acid compound with a molecular formula of C₇H₆O₃. It consists of a benzene ring, a carboxyl group, and an ortho-hydroxyl group, and has weak acidity and certain antibacterial properties. The compound is easily soluble in alcohol, ether, and hot water, and is often used as a chemical intermediate in industry and laboratories.
The color darkens in the sun, and turns into a purple-red chelate when it encounters iron ions. It reacts with ferric chloride to form purple. It is unstable to heat and is easily decarboxylated to generate phenol when heated to 200°C. In nature, salicylic acid mostly exists in birch bark oil in the form of methyl esters, with a content of up to 96%. It also exists in cinnamon oil, violet oil, and wintergreen oil. Only a small amount of free salicylic acid exists in plants.
