The product has active chemical property, and can lead to double bond addition reaction. It can react with inorganic or organic compounds containing active hydrogen to produce a series of cyanoethylation products. It is easy to polymerize in the absence of oxygen or exposed to visible light, and can be drastically polymerized in the presence of concentrated alkali. It reacts drastically with reducing agent to release toxic gas.
