Methyl cyanoacrylate (MCA) is an organic compound that contains several functional groups, a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.^[1] It can be encountered under many trade names. Methyl cyanoacrylate is less commonly encountered than ethyl cyanoacrylate.

It is soluble in acetone, methyl ethyl ketone, nitromethane, and dichloromethane.^[2] MCA polymerizes rapidly in presence of moisture.

Safety

Heating the polymer causes depolymerization of the cured MCA, producing gaseous products strongly irritant to lungs and eyes.
