Description4-Bromobenzaldehyde, a bifunctional aromatic with para-bromo and aldehyde. The aldehyde undergoes condensation, oxidation, and reductive amination; the bromide is a classic substrate for Pd-catalyzed Suzuki, Stille, and Buchwald-Hartwig couplings. Key intermediate for biphenyls, diarylamines, and polysubstituted arenes.
ApplicationsOLED intermediate; pharmaceutical intermediate; Suzuki coupling substrate; aldehyde building block
