4-Fluoro-4′-methoxybenzophenone (CAS 345-89-1) from Ossila is a fluorinated benzophenone building block carrying a fluorine atom and a methoxy group at the two para-positions. Supplied as white crystals with >98% purity, it serves researchers working in organic electronics, polymer chemistry and photocatalytic chemistry.
Because benzophenone derivatives respond to light, this compound can act as a photocatalyst in photochemical fluorination reactions that use sulfur hexafluoride as the fluorine source. Under 365 nm UV irradiation, this route gives a moderate yield of 56%.
The compound is also a precursor to fluorenone, a fluorene derivative bearing a ketone at the 9-position that is used in the pharmaceutical industry and in organic electronics. Fluorenone is obtained through palladium-catalysed dehydrogenative cyclization with yields of up to 90%. Its multiple functional groups also make it useful in the preparation of polyketone esters.
- Photocatalyst for photochemical fluorination using sulfur hexafluoride under 365 nm UV light.
- Starting material for fluorenone via palladium-catalysed dehydrogenative cyclization.
- Building block for polyketone ester synthesis.
- Intermediate for fluorene derivatives in organic electronics research.
