Its unique combination of chemical structure and physical properties makes it a valuable asset for researchers and industrial chemists alike. For those looking to understand this compound better and to buy it for their applications, exploring its scientific underpinnings is key. As a dedicated manufacturer and supplier of specialty chemicals, we provide high-quality TEAI and insights into its applications.

Chemical Structure and Nomenclature

Tetraethylammonium Iodide is an organic salt with the chemical formula C8H20N+I-. It comprises the tetraethylammonium cation ([CH3CH2]4N+) and the iodide anion (I-). The cation features a central nitrogen atom covalently bonded to four ethyl groups, resulting in a positively charged species. This ionic nature dictates many of its properties. The CAS Number for Tetraethylammonium Iodide is 68-05-3.

Key Physical and Chemical Properties

The utility of TEAI is rooted in its distinct physical and chemical characteristics:

  • Appearance: It typically appears as a white to off-white crystalline solid.
  • Purity: Commercial grades often reach high purities, exceeding 98% or 99%, which is crucial for its demanding applications.
  • Melting Point: TEAI exhibits a high melting point, often reported as greater than 300°C, sometimes with decomposition. This high thermal stability is beneficial in many reaction conditions.
  • Solubility: The compound is soluble in polar solvents such as water, methanol, and ethanol, enabling its use in aqueous and polar organic reaction systems.
  • Ionic Nature: As a salt, it dissociates in solution, providing mobile cations and anions that are essential for its roles in catalysis and electrochemistry.

Diverse Industrial Applications of TEAI

The unique properties of Tetraethylammonium Iodide lend themselves to a broad spectrum of applications:

  • Phase Transfer Catalysis (PTC): TEAI is a highly effective phase transfer catalyst. It transports anionic reactants from an aqueous phase to an organic phase, or vice versa, facilitating reactions that would otherwise be slow or impossible due to phase immiscibility. This is critical in organic synthesis for reactions like alkylations, acylations, and nucleophilic substitutions. When considering your next purchase, looking for competitive Tetraethylammonium Iodide prices from a reliable supplier is advisable.
  • Electrochemistry: In electrochemical research, TEAI serves as a vital supporting electrolyte. Its high ionic conductivity and wide electrochemical window contribute to stable and accurate measurements in techniques such as cyclic voltammetry, potentiometry, and the study of electrochemical processes.
  • Pharmaceuticals: TEAI can be used in pharmaceutical formulations to enhance the solubility and bioavailability of certain drug molecules through ion-pairing. It also acts as a key intermediate in the synthesis of various Active Pharmaceutical Ingredients (APIs).
  • Materials Science: It is utilized in the synthesis of ionic liquids and as a component in other advanced materials, benefiting from its ionic character and thermal stability.
