Octyl cyanoacrylate
Encyclopedia
Octyl cyanoacrylate 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. It can be encountered under various trade name
s including GluStitch, derma+flex® QS™, SurgiSeal, FloraSeal, Octylseal, Dermabond, Nexaband, and others.
In medical and veterinary applications, the related compounds n-butyl cyanoacrylate
and isobutyl cyanoacrylate
are commonly used. They 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.
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.

Ester
Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and...

Butyl cyanoacrylate
n-Butyl cyanoacrylate , a cyanoacrylate ester, is a butyl ester of 2-cyano-2-propenoic acid. It is a clear colorless liquid with a sharp, irritating odor. It is insoluble in water. Its chief use is as the main component of medical cyanoacrylate glues. It can be encountered under various trade...
and isobutyl cyanoacrylate
Isobutyl cyanoacrylate
Isobutyl cyanoacrylate is an isomer of butyl cyanoacrylate. It is used in medical procedures either to close incisions and lacerations without the use of sutures, or as an adjunct to strengthen the suturing. This use is possible because it is a bactericidal liquid monomer which, in thepresence of...
