Uses, cx-Aminonitriles may be hydrolyzed to aminoacids, such as is done in producing ethylenediaminetetracetate (EDTA) or nittilotriacetate (NTA). In these cases, formaldehyde is utilized in place of a ketone in the synthesis. The principal use of the ketone-based aminonitriles described above is in the production of azobisnittile radical initiators (see below). AN-64 is also used as an intermediate in the synthesis of the herbicide Bladex. Aminonitriles are also excellent intermediates for the synthesis of substituted hydantoins by reaction with carbon dioxide however, this is not currently commercially practiced.

This feature allows the farmer to plant other trlazine susceptible crops if his first crop is lost because of environmental factors. Other physical properties that are changed because of the presence of the cyano group are a nearly 5-fold increase in water solubility (Atrazine-33ppm, Bladex=160 ppm) and an approximate 200-fold decrease in the vapor pressure (Atrazine=3.0xl0 mm,Bladex-l.6x10 mm). ... 

Clearly terbufos, the first entry in the Table, is the most persistent with a T. <- of more than 35 days. Alkyl substitution on the carbon between the sulfur atoms of those molecules containing a nitrile group increases the soil persistence. Still, none are as persistent as terbufos. Therefore, the presence of a nitrile in these molecules, as was previously discussed for the Atrazine/ Bladex-triazine relationship, decreases the soil persistence of these organophosphorodithioates compared to terbufos.
