Description

Tetrakis(3-Aminopropyl)Ammonium is a multifunctional, quaternary ammonium compound featuring four primary amine-terminated propyl arms attached to a central nitrogen cation. This unique structure makes it a valuable building block and modifier in advanced material synthesis and specialty chemical manufacturing. It is particularly sought after by industries involved in polymer science, surface modification, and the development of functional additives. Its high amine functionality and cationic nature enable its use in creating cross-linked networks, enhancing adhesion, and imparting specific chemical properties to final products.

Application

• As a cross-linking agent or curing agent for epoxy resins and other polymers, enhancing thermal and mechanical properties.
• As a key monomer or modifier in the synthesis of dendrimers, hyperbranched polymers, and polyamidoamine (PAMAM) derivatives.
• For surface functionalization of materials like silica, carbon nanotubes, or graphene to improve dispersion and interfacial adhesion in composites.
• In the preparation of cationic flocculants or retention aids for water treatment and papermaking processes.
• As an intermediate for pharmaceutical and agrochemical actives, leveraging its multiple reactive amine sites.
• In the formulation of corrosion inhibitors and specialty coatings where its amine groups can chelate metals and promote adhesion.
• For the development of gene delivery vectors or non-viral transfection agents in biotechnological research.
• As a catalyst or phase-transfer agent in organic synthesis reactions.

Quality Control

Our Tetrakis(3-Aminopropyl)Ammonium is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications such as assay (by titration or HPLC), residual solvent content, and appearance. We support customer audits and can provide material to meet specific research, technical, or developmental grade requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
