Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) like ketoprofen. Its structure allows for efficient introduction of aromatic and carbonyl functionalities in organic reactions. Commonly employed in Friedel-Crafts acylation and bromination reactions to build complex aromatic compounds. Also utilized in the development of photoinitiators for polymer chemistry due to its ability to generate radicals under UV light. Serves as a building block in the preparation of liquid crystals and other specialty chemicals requiring biphenyl or benzophenone motifs.
