Ecotoxicology Acrolein is the simplest unsaturated aldehyde. It is an important intermediate in the production processes of a variety of substances. The main use of isolated acrolein is in the production of d,l-methionin, but in far more production processes, acrolein is used without purification. Acrolein is an extremely reactive chemical and, in very low concentrations, acts as a very effective broad-spectrum biocide. Methacrolein is produced commercially as an organic intermediate, which is used as building block for chain expansions or, in limited application, in the synthesis of flavors and fragrances.
