2-Octanyl cyanoacetate is an important organic compound with the chemical formula C₁₁H₁₉NO₂. It is primarily used as a key raw material in the synthesis of α-cyanoacrylate adhesives (i.e., the base material for "super glue" or "502 glue"), and is widely applied in orthodontics, dental restorations, and orthopedic artificial joint fixation. It is prepared by reacting 2-octanol with cyanoacetic acid.
