Efficient Fluorination Reagent: Mild Fluorination Ability, Suitable for Acid Sensitive Reaction Systems (such as Silane Protective Group Removal). Low volatility: Compared to anhydrous HF, it is safer and reduces operational risks.
Solubility: soluble in polar organic solvents such as acetonitrile and DMF, slightly soluble in water.
Compatibility: Compatible with various organic substrates and metal catalysts.
Used for organic synthesis of fluorinating reagents, glass etchants, battery electrolyte additives, semiconductor cleaning agents, etc., in the following fields:
Organic synthesis: removal of silicon protecting groups (such as TBS and TMS ether); Fluorination reaction (such as electrophilic fluorination of aromatic compounds).
Electronics industry: glass/quartz surface etchants, semiconductor wafer cleaning (removal of oxide residues).
Energy materials: Lithium ion battery electrolyte additives (to enhance SEI film stability).
