Benzoic acid (/ b ɛ n ˈ z oʊ. ɪ k /) is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent.
The molecular formula C 7 H 6 O 2 (molar mass: 122.12 g/mol, exact mass: 122.036779 u) may refer to: Benzoic acid; 1,3-Benzodioxole; Hydroxybenzaldehyde. Salicylaldehyde (2-hydroxybenzaldehyde) 3-Hydroxybenzaldehyde; 4-Hydroxybenzaldehyde; Tropolone

Benzoic acid is generally not used directly due to its poor water solubility. Concentration as a food preservative is limited by the FDA in the U.S. to 0.1% by weight. [ 8 ] Sodium benzoate is also allowed as an animal food additive at up to 0.1%, per the Association of American Feed Control Officials. [ 9 ]
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.
