Octyl cyanoacetate is an organic compound that exists as a colorless liquid at room temperature with a distinctive odor. It serves as a crucial chemical intermediate widely used in the synthesis of pharmaceuticals and dyes, and is also a key raw material for manufacturing cyanoacrylate-based instant adhesives (such as super glue) and pesticides. It is produced through the ester exchange reaction between cyanoacetic acid and n-octanol, forming a functional molecule containing both a cyano group and an ester group.
