Cyanate ester
open-in-new
<p>Cyanate esters are <a href="/facts/Chemical_compound/37FXqqtv">chemical compounds</a> in which the <a href="/facts/Hydrogen/BoYHjl0J">hydrogen</a> atom of the <a href="/facts/Cyanic_acid/up52qydJ">cyanic acid</a> is replaced by an <a href="/facts/Organyl/gqCNaN45">organyl</a> group (for example <a href="/facts/Aryl/M3z7QRXd">aryl</a> group). The resulting compound is termed a <a href="/facts/Cyanate/EcDWGQQh">cyanate</a> <a href="/facts/Ester/FoUAIIw4">ester</a>, with the formula R−O−C≡N, where R is an organyl group. Cyanate esters contain a <a href="/facts/Monovalent_ion/ck7cHByj">monovalent</a> cyanate group −O−C≡N. </p>
