Octyl cyanoacrylate (OCA), a cyanoacrylate ester, is an octyl ester of 2-cyano-2-propenoic acid. It is a clear colorless liquid with a sharp, irritating odor. Its chief use is as the main component of medical cyanoacrylate glues.

In medical and veterinary applications, octyl cyanoacrylate, n-butyl cyanoacrylate and isobutyl cyanoacrylate are commonly used. They provide rapid wound closure,[1] are bacteriostatic, and their use is usually painless. Butyl esters provide a stronger bond, but the glue is rigid. The octyl ester, while providing weaker bond, is more flexible. Blends of octyl cyanoacrylate and n-butyl cyanoacrylate are available which offer both flexibility and a strong bond.

It polymerizes rapidly in presence of moisture.

Heating to higher temperatures causes pyrolysis and depolymerization of the cured glue, producing gaseous products strongly irritating to lungs and eyes.
