Description

Tetraethylammonium Sulfate is a high-purity quaternary ammonium salt widely utilized as a phase-transfer catalyst and electrolyte in advanced chemical synthesis and electrochemical applications. Its primary value lies in its ability to facilitate reactions between reagents in immiscible phases and to serve as a supporting electrolyte in non-aqueous systems. This compound is essential for researchers and manufacturers in the pharmaceutical, specialty chemical, and battery technology sectors who require reliable, high-performance ionic materials.

Application

• Phase-Transfer Catalyst (PTC): Crucial for accelerating organic synthesis reactions, such as alkylations, esterifications, and nucleophilic substitutions, by transferring reactants between aqueous and organic phases.
• Electrochemical Research: Serves as a key supporting electrolyte in non-aqueous electrochemistry for studying redox processes, capacitor development, and battery material testing.
• Ionic Liquid & Material Science: Used as a precursor or additive in the formulation of ionic liquids and functional materials for specialized separation and conductive applications.
• Biochemical & Pharmaceutical Synthesis: Employed in the synthesis of complex molecules where controlled ionic strength and catalytic activity are required.
• Analytical Chemistry: Functions as an ion-pairing agent in chromatographic techniques like HPLC for the separation of ionic compounds.

Quality Control

Our Tetraethylammonium Sulfate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including purity by titration, identification by FT-IR, and limits for key impurities such as moisture and heavy metals. A Certificate of Analysis (COA) is supplied with each shipment, confirming compliance with our stringent specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent absorption of water, which can affect purity and performance.
