CAS 1643-19-2 Tetrabutylammonium Bromide (TBAB) Phase Transfer Catalyst Tetra-Butyl Ammonium Bromide

Product Description

Tetrabutylammonium Bromide (TBAB) Overview

Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt commonly used as a phase transfer catalyst, surfactant, and reagent in various chemical reactions. Its ability to transfer reactants between immiscible phases makes it particularly useful in organic synthesis, electrochemistry, and industrial applications.

Technical Data

Features

Phase Transfer Catalyst: Facilitates the transfer of reactants between immiscible phases (e.g., aqueous and organic).
High Solubility: Readily dissolves in water and polar solvents.
Thermally Stable: Can be used in reactions requiring moderate heat.
Versatility: Compatible with a wide range of chemical systems.
Hygroscopic: Requires proper storage to maintain stability.

Applications

1. Organic Synthesis

Phase Transfer Catalyst (PTC): Used in reactions such as alkylations, esterifications, and oxidations.
Nucleophilic Substitution Reactions: Enhances reactivity of nucleophiles in organic phase.
Polymerization: Acts as a catalyst in the synthesis of specialty polymers.

2. Electrochemistry

Electrolyte: Used as a supporting electrolyte in electrochemical studies and reactions.
Ionic Liquids: Serves as a precursor for the synthesis of ionic liquids.

3. Pharmaceuticals

Used in the synthesis of active pharmaceutical ingredients (APIs) and intermediates.

4. Industrial Applications

Extraction Processes: Assists in separating compounds from complex mixtures.
Surfactant: Used in formulations requiring surface-active agents.

5. Analytical Chemistry

Employed in chromatographic and spectrophotometric analyses to enhance separation or detection.
