For procurement professionals and R&D scientists in the chemical industry, securing a reliable supply of high-quality chemical intermediates is fundamental to operational success. Tetraethylammonium Iodide (TEAI), a versatile quaternary ammonium salt, is one such critical compound widely used as a phase transfer catalyst, an electrolyte in electrochemistry, and an intermediate in various syntheses. This guide aims to assist buyers in understanding the key considerations when sourcing TEAI, with a focus on quality, applications, and the benefits of partnering with reputable manufacturers.

Understanding Tetraethylammonium Iodide (TEAI)

Tetraethylammonium Iodide (CAS 68-05-3) is a chemical compound with the formula C8H20N+I-. It presents as a white to off-white crystalline solid. Its primary utility stems from its ability to facilitate reactions between immiscible phases, acting as a phase transfer catalyst. This capability significantly enhances reaction rates and yields in a variety of organic synthesis processes. Beyond catalysis, TEAI is also recognized for its use as a supporting electrolyte in electrochemical studies and as a component in pharmaceutical formulations.

Key Specifications to Consider When Buying TEAI

When evaluating suppliers and products, several specifications are crucial for ensuring the suitability of TEAI for your intended application:

• Purity: This is arguably the most important factor. High-purity TEAI (typically exceeding 98% or 99%) is essential for sensitive applications like advanced organic synthesis and electrochemistry to ensure predictable and reproducible results. Impurities can interfere with catalytic activity or electrochemical stability.
• Appearance: While generally described as a white crystalline powder, variations in color (e.g., slightly yellowish) might indicate trace impurities. Always check the appearance against product specifications.
• Melting Point: A high melting point, often above 300°C, is characteristic of TEAI and can be an indicator of its purity and crystalline structure.
• Solubility: Its solubility in polar solvents like water and methanol is a key property for its application in various reaction media.
• CAS Number: Always verify the CAS number (68-05-3) to ensure you are sourcing the correct compound.

Applications Driving Demand for TEAI

The demand for Tetraethylammonium Iodide is driven by its effectiveness across multiple sectors:

• Organic Synthesis: As a phase transfer catalyst, it promotes alkylation, nucleophilic substitutions, and other reactions involving reagents in different phases.
• Electrochemistry: It serves as a reliable supporting electrolyte, enhancing conductivity and stability in electrochemical cells.
• Pharmaceuticals: TEAI is used to improve the solubility and bioavailability of certain drug compounds and acts as an intermediate in API synthesis.
• Materials Science: It finds applications in the development of ionic liquids and other specialty materials.
