Description

Tetraethylammonium Fluoride Tetrahydrofluoride is a versatile fluorinating agent and a source of anhydrous fluoride ions. This compound is particularly valued for its role as a strong, non-nucleophilic base in organic synthesis, enabling critical deprotonation and substitution reactions. It is an essential reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, reactive fluoride chemistry.

Application

• Fluorination Reactions: A key reagent for nucleophilic fluorination, particularly in the synthesis of fluorinated aromatic compounds and heterocycles.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, especially in halogen exchange (halex) reactions to introduce fluorine atoms.
• Organic Synthesis Intermediate: Used in the preparation of complex molecules, including active pharmaceutical ingredients (APIs) and specialty chemicals.
• Polymer Chemistry: Employed as a catalyst or initiator in the synthesis of specific fluorinated polymers and advanced polymeric materials.
• Electrolyte Additive: Investigated for use in lithium-ion battery electrolytes to improve stability and performance at the electrode interface.
• Laboratory Research: Serves as a fundamental reagent in academic and industrial R&D for developing new fluorination methodologies.

Quality Control

Our Tetraethylammonium Fluoride Tetrahydrofluoride is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and moisture content determination, to ensure high purity and batch-to-batch consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent decomposition. Recommended long-term storage temperature is 2-8°C.
