4-Fluorophenylboronic acid (Cat No.: R040505) is an organoboron compound featuring a fluorine atom at the para-position of a phenyl ring and a boronic acid functional group. It is widely used as a key reagent in Suzuki-Miyaura cross-coupling reactions for constructing biaryl and aryl-heteroaryl linkages in pharmaceuticals, agrochemicals, and advanced materials. The para-fluoro substitution enhances its electronic properties and reactivity, supporting selective transformations. This compound is valued for its stability and ease of handling in palladium-catalyzed processes. For laboratory research and synthesis only.
