Potassium Fluoride 99% Purity White Crystalline Powder Chemical Industry and Glass Etching High Quality Potassium Fluoride CAS 7789-23-3 Reagent Grade

Product Overview

Potassium fluoride (CAS 7789-23-3) is a white, deliquescent crystalline powder with a saline taste. The molecular formula is KF with a molecular weight of 58.10 g/mol . It is highly soluble in water (approximately 923 g/L at 20°C) and readily absorbs moisture from the air, requiring careful storage in sealed containers . Its aqueous solution is alkaline and can corrode glass and porcelain, which necessitates handling with appropriate protective equipment . As a reagent-grade product supplied at a minimum purity of 99.0%, it serves as a versatile inorganic salt in various chemical synthesis applications, particularly as a fluorinating agent and as a source of fluoride ions. It is available in 500g laboratory bottles and 25kg industrial bags .

Synthetic Process

Potassium fluoride is typically produced by the neutralization of hydrofluoric acid with potassium hydroxide or potassium carbonate, followed by crystallization and drying. The product is carefully dried to maintain low moisture content and prevent the formation of hydrates (KF·2H₂O or KF·4H₂O) . The anhydrous form is stabilized by maintaining strict control over storage conditions to prevent deliquescence.

Mechanism of Action / Application Principles

As a chemical reagent, potassium fluoride functions through several key mechanisms:

• Fluorinating Agent: Potassium fluoride serves as a source of fluoride ions for various fluorination reactions in organic synthesis, including the preparation of organofluorine compounds and sulfonyl fluorides .

• Nucleophilic Fluorination: The fluoride ion acts as a nucleophile in substitution reactions, enabling the synthesis of fluorinated organic compounds. The anhydrous form is preferred for these applications due to its higher reactivity.

• Catalyst and Complexing Agent: It functions as a catalyst in certain organic transformations and as a complexing agent for the formation of coordination compounds .

• Analytical Applications: Potassium fluoride is used in analytical chemistry as a reagent for the detection of certain metal ions and as a fermentation inhibitor in biochemical analysis .
