Description

N-(3-Aminopropyl)diethanolamine is a versatile amino alcohol compound with a unique bifunctional structure containing both primary amine and secondary hydroxyl groups. This molecular architecture makes it a valuable intermediate for synthesizing specialized surfactants, chelating agents, and corrosion inhibitors. It is particularly sought after by formulators and chemical manufacturers in the personal care, agrochemical, and water treatment industries for its ability to impart cationic and amphoteric properties.

Application

• Surfactant Intermediate: Key building block for manufacturing amphoteric and cationic surfactants used in personal care products (shampoos, conditioners) and industrial cleaners.
• Corrosion Inhibitor Formulation: Used in the synthesis of filming amines and other compounds that protect metal surfaces in cooling water systems and boiler treatments.
• Chelating Agent Precursor: Serves as a starting material for producing polyamino carboxylate chelants, useful in water softening and scale inhibition.
• Epoxy Curing Agent Modifier: Acts as a reactive diluent and hardener modifier in epoxy resin systems, improving flexibility and adhesion.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and pesticide compounds.
• Gas Treating Agent: Utilized in formulations for acid gas (CO2, H2S) scrubbing in natural gas processing and refining.
• Polymer Additive: Functions as a chain extender or crosslinking agent in polyurethane and polyurea elastomers.
• Textile & Leather Auxiliary Chemicals: Used in the production of softeners, dye-fixing agents, and finishing chemicals.

Quality Control

Our N-(3-Aminopropyl)diethanolamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, water content, and color are available upon request to support your quality assurance protocols.

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 initial use to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong oxidizing agents and acids.
