Description

1,4,7,10,13-Pentaazatridecane is a linear pentaamine compound, also known by its common name tetraethylenepentamine (TEPA). This versatile polyamine is a critical intermediate and functional additive valued for its strong chelating and cross-linking properties. It is essential for manufacturers in sectors requiring high-performance polymers, corrosion inhibitors, and specialized chemical synthesis. The compound is supplied with CAS No. 112-57-2.

Application

• Epoxy Curing Agent & Hardener: A key component in epoxy resin systems, providing excellent cross-linking for coatings, adhesives, and composite materials.
• Chelating Agent: Used in water treatment, textile processing, and metal finishing to sequester metal ions like copper, nickel, and cobalt.
• Corrosion Inhibitor Intermediate: Serves as a building block for formulating high-efficiency corrosion inhibitors used in fuel additives, lubricants, and industrial coolants.
• Polyamide Resin Production: A monomer for synthesizing polyamide resins used in hot-melt adhesives, inks, and flexible packaging.
• Pharmaceutical & Agrochemical Synthesis: An intermediate in the production of certain active pharmaceutical ingredients (APIs) and agrochemicals.
• Gas Treating Agent: Employed in gas scrubbing processes for the removal of acidic components like CO₂ and H₂S.
• Paper & Textile Chemical: Used as a wet-strength resin additive for paper and as a dye-fixing agent in textiles.

Quality Control

Our 1,4,7,10,13-Pentaazatridecane is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis via gas chromatography (GC), to ensure it meets precise specifications for industrial and technical applications. Certificates of Analysis (COA) documenting purity, color, and density 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 to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong acids and oxidizing agents.
