4-Chlorobenzophenone (Cat No.: R021084) is an aromatic ketone composed of a benzophenone core with a chlorine atom substituted at the para (4) position on one of the phenyl rings. It appears as a white to pale yellow crystalline solid and is used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. The para-chloro substitution enhances its reactivity in electrophilic aromatic substitution and cross-coupling reactions. It also serves as a building block for UV absorbers and other photoactive compounds in industrial applications.
