3-Oxocyclobutanecarbonitrile（Cat No.:L014789）is a small organic molecule with a four-membered cyclobutane ring bearing both a ketone group (oxo) and a nitrile (-CN) group. Its structure provides a unique combination of ring strain and electron-withdrawing functionality, making it a versatile intermediate in pharmaceutical and agrochemical synthesis. The oxo and cyano groups enhance its reactivity toward nucleophilic additions and condensations. This compound is especially useful in building substituted cyclobutanes, spiro compounds, and heterocycles. Due to its strained ring, it may also serve as a precursor for ring-opening reactions in material and medicinal chemistry applications.
