A fluorinated four-membered ring building block

Used as a precursor for bioimaging fluorescent dyes and energetic materials

Overview
Related Products

3,3-Difluoroazetidine hydrochloride (CAS number 288315-03-7) is a derivative of azetidine, a four-membered ring heterocyclic compound with three carbons and one nitrogen. Two fluorine-substituents on the 3-position of azetidine make the molecule more lipophilic, improving the solvent processability. The ring strain of azetidine (27.7 Kcal/mol) enhances the accessibility of the nitrogen electron lone pair, which allows it for stronger nucleophilic attacks (increases reaction rate), compared to other secondary amine species.

3,3-Difluoroazetidine hydrochloride is used as a precursor for rhodamine dyes to finely tune their fluorescent wavelengths in bioimaging applications. It has a high potential to expand the use in application of OLEDs and DSSCs (dye-sensitized solar cells), due to its ability of tuning the HOMO-LUMO (highest occupied molecular orbital and lowest unoccupied molecular orbital) energy gap.

Another application of 3,3-difluoroazetidine hydrochloride is for synthesizing triazolyl polycyclic energetic materials (combustion applications) for improving the stability and density.
