Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions where it serves as a protected form of 4-nitrophenylboronic acid. The esterification with 1,3-propanediol enhances stability and reduces protodeboronation, making it more suitable for palladium-catalyzed reactions in the preparation of biaryl compounds. Commonly applied in pharmaceutical and agrochemical synthesis where controlled reactivity and improved handling of boronic species are required. Also utilized in the development of sensors and functional materials due to the nitro group’s ability to act as an electron-withdrawing moiety and spectroscopic probe.
