4-Bromoisoxazole(CAT: L014283) is a halogenated heteroaromatic compound featuring a five-membered isoxazole ring substituted with a bromine atom at the 4-position. This compound is a valuable intermediate in organic synthesis, particularly in the development of pharmaceuticals, agrochemicals, and bioactive heterocycles. The electron-deficient nature of the isoxazole ring, combined with the bromine atom, makes it amenable to cross-coupling reactions such as Suzuki, Stille, and Heck protocols. 4-Bromoisoxazole is frequently used in constructing kinase inhibitors, CNS-active agents, and anti-inflammatory molecules. Its versatile reactivity and compact heterocyclic framework support medicinal chemistry and structure–activity relationship (SAR) studies in drug discovery programs.
