Application
3,5-Difluorotoluene (1,3-difluoro-5-methylbenzene, CAS 117358-51-7) is a halogenated toluene derivative. As a crucial fluorinated building block, it is extensively used as a pharmaceutical intermediate for the synthesis of rufinamide (anticonvulsant), tigecycline (antibiotic), efavirenz (antiviral), and fosfluconazole (antifungal). In agrochemistry, it serves as a key precursor for herbicides (flucarbazone) and fungicides (fludioxonil). Its fluorinated aromatic structure also makes it valuable in material science as a monomer for high-performance polymers and as a precursor for liquid crystal display materials.
