Description

Triethylenetetramine (CAS NO 112-24-3) is a versatile aliphatic polyamine with four amine groups, making it a highly effective crosslinking agent and chelating compound. Its primary value lies in its ability to form strong, durable covalent bonds and stable complexes with metal ions, which is critical for creating high-performance materials and purification processes. This chemical is essential for manufacturers in the epoxy resin curing, chelating agent production, textile, and water treatment industries seeking reliable and reactive intermediates.

Application

• Epoxy Resin Curing Agent: A key hardener for epoxy resins, providing excellent mechanical strength, chemical resistance, and thermal stability in coatings, adhesives, and composite materials.
• Chelating Agent Precursor: Used in the synthesis of chelating agents like EDTA analogs for water treatment, detergent formulations, and industrial cleaning to sequester metal ions.
• Corrosion Inhibitor: Formulated into protective coatings and additives for metal surfaces in industrial cooling systems and pipelines.
• Textile Auxiliary: Acts as a dye-fixing agent and crosslinker in the production of wrinkle-resistant and durable-press fabrics.
• Ion Exchange Resin Intermediate: Serves as a functional monomer in the manufacture of specialty ion exchange resins for water purification and metal recovery.
• Pharmaceutical & Agrochemical Intermediate: Used in the synthesis of certain active pharmaceutical ingredients (APIs) and agricultural chemicals.
• Gas Purification: Employed in scrubbing processes to remove acidic gases like CO2 and H2S from natural gas streams.
• Rubber Vulcanization Accelerator: Functions as an accelerator in the vulcanization of synthetic rubbers.

Quality Control

Our Triethylenetetramine is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against comprehensive specifications, including assay, color, and impurity profiles. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is 15-25°C.
