Aure Chemical supplies high-purity Boron Trifluoride Diethyl Etherate Complex (BF₃·OEt₂), CAS 109-63-7. This indispensable Lewis acid is a core catalyst for organic synthesis (esterification, alkylation), vital for synthetic rubber and resin production (e.g., polyformaldehyde), and a key raw material for borane compounds (high-energy fuels).
