Phenylic acid is also known as benzoic acid, which belongs to the aromatic carboxylic acid group. It is commonly found in several natural sources like cranberries, cinnamon, and prunes. Benzenecarboxylic acid is another synonym for phenylic acid, which is widely used in several industries, including food, textile, and pharmaceuticals. Salicylic acid, an important component in several topical skin care products, is also a derivative of phenylic acid. Structurally related compounds like p-hydroxybenzoic acid, anthranilic acid, and toluic acid are some of the other synonyms for phenylic acid that are commonly used in scientific literature. These compounds have similar chemical properties and functional groups that make them useful for industrial applications.
