Oxalic acid is also known as ethanedioic acid. It is a colourless, crystalline, toxic organic compound belonging to the family of carboxylic acids. Oxalic acid is widely used as an acid rinse in laundries, where it is effective in removing rust and ink stains because it converts most insoluble iron compounds into a soluble complexion.

For the same reason, it is the chief constituent of many commercial preparations used for removing scale from automobile radiators. The formula of oxalic acid is (C2H2O4); its usual form is that of the crystalline hydrate, (COOH)2·2H2O. Known as a constituent of wood sorrel as early as the 17th century, oxalic acid was first prepared synthetically in 1776.
It is manufactured by heating sodium formate in the presence of an alkali catalyst, by oxidizing carbohydrates with nitric acid, by heating sawdust with caustic alkalies, or by fermentation of sugar solutions in the presence of certain moulds. Oxalic acid is thought to be a key factor of the early pathogenic stage in a wide range of necrotrophic fungi.
Oxalic acid Induces Programmed Cell Death (PCD) in Arabidopsis thaliana cells. This cell death results from an early anionic efflux which is a prerequisite for the synthesis of ethylene and the PCD. Phytopathogenic fungi such as Botrytis cinerea and Sclerotinia sclerotium are capable of infecting numerous plants. The infection by these fungi leads to considerable losses at harvest time.
