They are also good solvents for spinning and casting and extractive distillation based on its selective miscibility with organic compounds and can act as removing agents of colouring matters and aromatic alcohols. Inorganic cyanides are also able to perform a recrystallization of steroids or to be compounds for organic synthesis. Therefore, they basically act as solvents or chemical intermediates in biochemistry (pesticide sequencing and DNA synthesis, for example). Some other useful applications of these organic nitriles are the performance of high-pressure liquid chromatographic analysis. Also, the action they have as catalysts and components of transition-metal complex catalysts, stabilizers for chlorinated solvents. Furthermore, they may work as chemical intermediates and solvents for perfumes and pharmaceutical products.
