2,3-Difluorotoluene is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its fluorinated structure makes it valuable for introducing fluorine atoms into more complex molecules, which can enhance their biological activity, stability, and bioavailability. Additionally, it serves as a building block in the development of specialty chemicals, including dyes, polymers, and liquid crystals. Its unique properties also make it suitable for research purposes in the study of fluorinated aromatic compounds and their reactivity.
