Potassium fluoride

Potassium fluoride (CAS 7789-23-3), commonly abbreviated as KF, is an inorganic fluoride salt.

Where is Potassium fluoride used?

• Chemical synthesis: fluorinating agent, flux and catalyst where controlled fluoride ion delivery is required
• Pharmaceutical and fine chemical synthesis: nucleophilic fluorinating reagent enabling halogen-exchange reactions to introduce fluorine into active pharmaceutical ingredients and specialty intermediates
• Electronics: flux and surface treatment agent for metal components, improving solderability and removing oxide layers prior to assembly
• Textile and leather processing: preservatives and pH buffers that control microbial activity and maintain process bath conditions
• Flame retardant compounding draws on KF as a precursor or synergist in formulations targeting polymer and fiber substrates.

Commercial specifications

• Purity typically 98% to 99%+
• Moisture-resistant bags and drums suited to hygroscopic handling requirements
