Potassium fluoride

Potassium fluoride is a white, crystalline inorganic compound widely used in chemical laboratories and pharmaceutical research, particularly known for its role as a fluoride ion source in synthesis and analytical procedures.

🏭⚗️ Production
Potassium fluoride is typically produced by the neutralization of hydrofluoric acid with potassium hydroxide, forming potassium fluoride and water. This process is performed under controlled laboratory conditions due to the corrosive nature of hydrofluoric acid.

🔬 Properties
The chemical formula is KF, with a molar mass of approximately 58.10 g/mol. Potassium fluoride appears as a white, hygroscopic crystalline powder, is highly soluble in water, and slightly soluble in alcohol. It has a melting point of about 858 °C and a boiling point of approximately 1502–1505 °C. In aqueous solution, it dissociates completely into potassium and fluoride ions, making it a strong electrolyte.

🧪 Applications
In laboratory and pharmaceutical contexts, potassium fluoride is primarily used as a reagent in organic synthesis, particularly for introducing fluorine atoms into molecules via nucleophilic substitution reactions. It is essential in the preparation of organofluorine compounds, which are of significant interest in medicinal chemistry for their metabolic stability and bioactivity. Additionally, it is used in analytical chemistry for fluoride ion detection and as a catalyst or phase-transfer agent in various reactions.

⚠️ Safety
Potassium fluoride is highly toxic and corrosive and must be handled with extreme care in laboratory environments. It can cause severe burns upon skin or eye contact and is harmful if inhaled or ingested. Fluoride toxicity may lead to symptoms such as nausea, abdominal pain, hypocalcemia, or even systemic poisoning. It should be handled using appropriate personal protective equipment, including gloves, lab coat, and eye protection, and stored in a tightly sealed container away from moisture and acids.
