Benzoic Acid

Benzoic acid ( /bɛnˈzoʊ.ɪk/), C₇H₆O₂ (or C₆H₅COOH), is a colorless crystalline solid and a simple aromatic carboxylic acid. The name derived from gum benzoin, which was for a long time the only source for benzoic acid. Its salts are used as a food preservative and benzoic acid is an important precursor for the synthesis of many other organic substances. The salts and esters of benzoic acid are known as benzoates ( /ˈbɛnzoʊ.eɪt/).
