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.
Maleic hydrazide, often known by the brand name Fazor is a plant growth regulator that reduces growth through preventing cell division but not cell enlargement. [ 1 ] [ 2 ] It is applied to the foliage of potato, onion, garlic and carrot crops to prevent sprouting during storage. [ 3 ]
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 ...
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 Many insecticides have been banned or otherwise withdrawn from the market over the decades.
It can be described as the double ester of maleic acid with the alcohol 2-ethylhexanol. It is commonly called dioctyl maleate (DOM), reflecting the older usage of "octane" to refer to any 8-carbon alkane, straight-chained or branched. The compound is manufactured by treating 2-ethylhexanol with maleic anhydride and an
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 ...

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
For the synthesis of tetrasodium iminodisuccinate, maleic anhydride is reacted with sodium hydroxide in water at elevated temperature. A concentrated disodium maleate solution is formed to which ammonia is added [ 4 ] at 90 to 145 °C, then excess water and ammonia is distilled off.
