Dytek® 2PN, also recognized as 2-Pentenenitrile, serves diverse roles in various chemical applications. It acts as an intermediate in the production of ethyl-branched fatty diamines, ether nitriles, and ether amines, as well as 1,3-pentanediamine. Furthermore, it functions as a monomer, curative, and amine extender. Its versatility extends to pyridine derivatives, pentylamines, and penteneamide.
