Description

Tetrakis(2-Hydroxyethyl)Ammonium Bromide is a quaternary ammonium salt characterized by its four hydroxymethyl functional groups. This structure makes it a versatile chemical intermediate and a valuable source of a cationic moiety for modifying material properties. It is primarily sought after by industries requiring phase transfer catalysts, polymer modifiers, or specialty surfactants. Its functionality is key in applications ranging from organic synthesis to the production of specialty resins and coatings.

Application

• As a phase transfer catalyst (PTC) in organic synthesis reactions, facilitating the migration of reactants between immiscible phases.
• As a cationic monomer or modifier in the synthesis of specialty polymers and resins, imparting water solubility or modifying surface properties.
• In the formulation of antistatic agents and fabric softeners for textiles and plastics.
• As a key intermediate for the preparation of other quaternary ammonium compounds with tailored functionalities.
• In research and development as a structure-directing agent for materials science applications.
• Potential use in the formulation of biocides and disinfectants, leveraging its quaternary ammonium structure.

Quality Control

Our Tetrakis(2-Hydroxyethyl)Ammonium Bromide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as assay, moisture content, and heavy metals. Our quality commitment ensures the material meets the stringent requirements for research and industrial synthesis.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
