Tetramethylammonium Iodide (TMAI), chemically known as N,N,N-Trimethylmethanaminium iodide and identified by CAS number 75-58-1, is a compound of significant interest in the chemical sector. As a product manufactured and supplied by NINGBO INNO PHARMCHEM CO., LTD., understanding its intrinsic properties is vital for its effective application. This article aims to shed light on what makes TMAI a valuable asset in various chemical processes.

Physically, TMAI is characterized by its appearance as a white crystal. Its molecular weight is approximately 201.049 g/mol, with an exact mass of 201.001434. A key feature is its remarkable stability, although it is sensitive to light and tends to absorb moisture from the air (hygroscopic). These attributes necessitate specific storage conditions: it should be kept in a cool, well-ventilated area, preferably in a dark, dry container, to maintain its 99% assay purity. The compound has a density of 1.84 g/cm³ at 20°C and a melting point exceeding 300°C, indicating its robustness under various conditions.

The solubility of TMAI in water is described as sparingly soluble. This characteristic is crucial for its most prominent application: acting as a cationic phase transfer catalyst. In phase transfer catalysis, TMAI facilitates the movement of ions or molecules between immiscible phases, typically aqueous and organic. The quaternary ammonium cation can complex with an anion from the aqueous phase, making it more soluble in the organic phase. This enables reactions that would otherwise be slow or impossible due to the phase barrier. This capability is invaluable in organic synthesis, where it can increase reaction rates, improve yields, and enhance selectivity. For example, reactions involving nucleophilic substitution or alkylation often benefit from the use of TMAI.

Beyond its role as a standalone catalyst, TMAI is a representative of a much larger family of quaternary ammonium salts developed by NINGBO INNO PHARMCHEM CO., LTD. The company's extensive portfolio includes over 200 variants, serving diverse industries such as oilfield chemicals and fine chemicals. This breadth of offerings underscores a commitment to innovation and customization, allowing clients to find precise solutions for their unique needs. The research and development efforts of NINGBO INNO PHARMCHEM CO., LTD. often focus on downstream applications of these quaternary ammonium salts, including emulsifiers for pesticides and specialized surfactants for daily chemicals, demonstrating the wide-reaching impact of compounds like TMAI.

Proper handling and storage are emphasized for TMAI to ensure its optimal performance. The company typically packages the product in 25 kg drums, adhering to the necessary precautions to preserve its quality. Customers are advised on its light sensitivity and hygroscopic nature, ensuring they can maximize the benefits of this versatile chemical in their processes.

In summary, Tetramethylammonium Iodide stands out due to its specific physical and chemical properties, most notably its effectiveness as a phase transfer catalyst. Its application in organic synthesis and broader chemical manufacturing highlights its importance as a key reagent. NINGBO INNO PHARMCHEM CO., LTD. is dedicated to providing high-quality TMAI and supporting advancements in chemical technology through its extensive product range and commitment to customer needs.
