ʻO ka ʻakika benzoic C7H6O2 (a i ʻole C6H5COOH), he paʻa kalakala kala ʻole a me ka waikawa carboxylic ʻala maʻalahi loa. Ua loaʻa ka inoa mai ka gum benzoin, ʻo ia wale nō ke kumu no ka benzoic acid no ka manawa lōʻihi. Hoʻohana ʻia kāna mau paʻakai ma ke ʻano he mea mālama meaʻai a ʻo ka benzoic acid kahi mea mua no ka synthesis o nā mea ola ʻē aʻe. ʻO nā paʻakai a me nā esters o ka benzoic acid i kapa ʻia he benzoates.
