Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-acrylic acid. It is a colorless liquid with low viscosity and a faint sweet smell in pure form. It is the main component of cyanoacrylate glues and can be encountered under many trade names . [ 2 ]
The compound 2-octyl cyanoacrylate degrades much more slowly due to its longer organic backbone (series of covalently bonded carbon molecules) and the adhesive does not reach the threshold of tissue toxicity. Due to the toxicity issues of ethyl cyanoacrylate, the use of 2-octyl cyanoacrylate for sutures is preferred. [33]
Ethyl acrylate is an organic compound with the formula CH 2 CHCO 2 CH 2 CH 3. It is the ethyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced for paints, textiles, and non-woven fibers. [5] It is also a reagent in the synthesis of various pharmaceutical intermediates.
Ethyl cyanoacetate is an organic compound that contains a carboxylate ester and a nitrile. It is a colourless [ 1 ] liquid with a pleasant odor. This material is useful as a starting material for synthesis due to its variety of functional groups and chemical reactivity.
Acrylates (IUPAC: prop-2-enoates) are the salts, esters, and conjugate bases of acrylic acid. The acrylate ion is the anion CH 2 =CHCO − 2 . Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate .

VCU (20-5, 10-2 Atlantic 10)** Oklahoma has won only three of its past 11 games after a 13-0 start. BYU has played its way onto the bubble with four wins in its past six games, including victories ...
In its largest scale application, cyanoacetic acid is first esterified to give ethyl cyanoacetate. Condensation of that ester with formaldehyde gives ethyl cyanoacrylate , which used as superglue. As of 2007, more than 10,000 tons of cyanoacetic acid were produced annually.
