3-Fluorophenyl isocyanate（Cat No.:R070614）is an aromatic isocyanate featuring a fluorine atom at the meta (3-) position on the phenyl ring relative to the isocyanate group (–N=C=O). This compound is a valuable intermediate in the synthesis of ureas, carbamates, and heterocycles, frequently used in pharmaceutical, agrochemical, and material science applications. The fluorine substituent influences the compound’s electronic properties, enhancing its reactivity and modulating biological activity in target molecules. Its isocyanate functionality readily reacts with nucleophiles such as amines and alcohols, making it ideal for constructing functionalized aromatic derivatives and structure–activity relationship (SAR) studies.
