Description

2-Ethoxyethyl-[2-[4-[4-[4-[2-(2-Ethoxyethyl-Dimethyl-Ammonio)Acetyl]Phenyl]Phenyl]Phenyl]-2-Oxo-Ethyl]-Dimethyl-Azanium Dibromide is a high-purity, symmetrical bis-quaternary ammonium salt with a unique extended aromatic structure. This compound is valued for its strong cationic properties and ability to interact with anionic surfaces, making it a critical functional intermediate in advanced material synthesis. It is primarily sought by research and development teams in the specialty chemical, pharmaceutical, and advanced polymer industries for creating novel cationic agents, phase-transfer catalysts, and functional monomers.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis and polymerization processes.
• Polymer Modification: Serves as a functional monomer or cross-linking agent to introduce permanent cationic charges into polymer backbones for specialty resins and ion-exchange materials.
• Surface Active Agent: Used in the formulation of cationic surfactants and emulsifiers for niche industrial applications requiring specific molecular architecture.
• Pharmaceutical Intermediate: Acts as a key building block in the synthesis of novel quaternary ammonium compounds with potential biological activity.
• Material Science Research: Employed in R&D for developing advanced materials like liquid crystals, conductive polymers, and self-assembling monolayers.
• Analytical Chemistry: Can be utilized as a standard or reagent in chromatographic methods and other analytical techniques for cationic compound analysis.
