3,4-Difluorostyrene, 98% (stabilized with TBC) features a dual fluorine substitution at the ortho positions of the phenyl ring, enhancing electron deficiency and metabolic stability. The para-vinyl group enables efficient coupling in cross-coupling reactions. Stabilized with TBC to inhibit polymerization during storage and handling. Bench-stable under standard conditions.
3,4-Difluorostyrene (98%, stabilized with TBC) serves as a valuable building block for fluorinated aromatic systems, enabling efficient incorporation of ortho-difluoro substitution into pharmaceutical and agrochemical scaffolds. The stabilizer (TBC) enhances shelf stability and handling safety, while the vinyl functionality facilitates robust cross-coupling reactions, including Suzuki-Miyaura and Heck processes. Its bench-stable nature and compatibility with standard reaction conditions make it a practical choice for synthetic chemists developing fluorinated heterocycles and bioactive molecules.
