Descrição geral

Salicylic acid is an aromatic phenolic derivative. It plays an important role in various physiological processes in plants, such as thermogenesis, ethylene synthesis and fruit ripening.[1]

Aplicação

Salicylic acid may be used for the quantitative estimation of nitrate in plant materials by colorimetric method.[2] It may be used in the synthesis of 2,5-dihydroxybenzoic acid (gentistic acid).[3]
