Description

General description

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.

Application

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