Description

3-Aminopropyl(Octyl)Amine (CAS NO 7173-57-1) is a versatile bifunctional amine featuring both a primary and a secondary amine group separated by a long alkyl chain. This unique structure makes it a valuable intermediate for synthesizing surfactants, corrosion inhibitors, and epoxy curing agents. It is particularly sought after by formulators and chemical manufacturers in the agrochemical, personal care, and polymer industries.

Application

• Surfactant and Detergent Intermediate: Used to synthesize cationic and amphoteric surfactants for personal care and industrial cleaning products.
• Corrosion Inhibitor Precursor: Acts as a key building block for creating film-forming amine-based corrosion inhibitors used in water treatment and oilfield applications.
• Epoxy Curing Agent / Hardener: Functions as a reactive amine hardener for epoxy resin systems, contributing to flexibility and improved chemical resistance.
• Agrochemical Intermediate: Employed in the synthesis of herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediate: Serves as a synthon in the production of various active pharmaceutical ingredients (APIs).
• Chelating Agent Synthesis: Used to produce ligands and chelating agents for metal ion sequestration.
• Polymer Modification: Utilized to introduce amine functionality into polymers for improved adhesion or reactivity.
• Fuel and Lubricant Additive: Acts as a dispersant or detergent additive in fuel and lubricant formulations.

Quality Control

Our 3-Aminopropyl(Octyl)Amine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to guarantee supply reliability and product traceability.

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 degradation from atmospheric moisture.
