Cas no 93343-10-3 (1,3-difluoro-5-methoxybenzene)
1,3-Difluoro-5-methoxybenzene is a fluorinated aromatic compound characterized by its methoxy and fluorine substituents at the 1, 3, and 5 positions of the benzene ring. This structure imparts unique electronic and steric properties, making it a valuable intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. The fluorine atoms enhance metabolic stability and lipophilicity, while the methoxy group offers reactivity for further functionalization. Its high purity and well-defined structure ensure consistent performance in cross-coupling reactions, nucleophilic substitutions, and other transformations. The compound is typically supplied as a clear liquid or solid with defined melting/boiling points, suitable for precise applications in research and industrial processes.
