Maleic anhydride is a classic substrate for Diels-Alder reactions. [9] It was used for work in 1928, on the reaction between maleic anhydride and 1,3-butadiene, for which Otto Paul Hermann Diels and Kurt Alder were awarded the Nobel Prize in 1950. It is through this reaction that maleic anhydride is converted to many pesticides and pharmaceuticals.
The compound is manufactured by treating 2-ethylhexanol with maleic anhydride and an esterification catalyst. It is a key intermediate raw material in the production of dioctyl sulfosuccinate (DOSS, docusate) salts, used medically as laxatives and stool softeners, and in many other applications as versatile surfactants.

The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been ...
In industry, maleic acid is derived by hydrolysis of maleic anhydride, the latter being produced by oxidation of benzene or butane. [4] Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. [8] Maleic acid may be used to form acid addition salts with drugs to make them more stable, such as indacaterol ...
Malic acid is an organic compound with the molecular formula HO 2 CCH(OH)CH 2 CO 2 H.It is a dicarboxylic acid that is made by all living organisms, contributes to the sour taste of fruits, and is used as a food additive.
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Other medical uses include treatment of breast cancer and its monitoring with Positron Emission Tomography. [8] It is also used as a food additive [9] and has Food and Drug Administration clearance for indirect food contact. In synthetic organic chemistry it is a dienophile and used in the Diels-Alder reaction.
The pesticide manual provides much information on pesticides. [6] [7] Many of the insecticides in the list are not in use. The developer of a pesticide applies for a common name when they intend to sell it, but some nevertheless do not reach the market. Many insecticides have been banned or otherwise withdrawn from the market over the decades.
