Description

Hexamethyleneimine is a versatile, nitrogen-containing heterocyclic compound, specifically a seven-membered cyclic secondary amine. This high-purity intermediate is critical for synthesizing advanced polymers, pharmaceuticals, and agrochemicals, where its reactive amine functionality enables key chemical transformations. It serves as an essential building block for manufacturers in the polymer, pharmaceutical, and specialty chemical industries seeking reliable, high-quality raw materials.

Application

• Polymer Industry: Key monomer for the production of nylon-6,6 and other polyamides; used as a chain extender and cross-linking agent in polyurethane and epoxy resin systems.
• Pharmaceutical Synthesis: Important intermediate in the manufacture of various active pharmaceutical ingredients (APIs), including certain antibiotics, antivirals, and cardiovascular drugs.
• Agrochemical Production: Used in the synthesis of herbicides, fungicides, and plant growth regulators.
• Corrosion Inhibitors: Component in formulations for metal surface treatment and corrosion protection, particularly in cooling water systems and oilfield applications.
• Organic Synthesis: Serves as a versatile building block and catalyst in organic reactions, including alkylation and as a ligand precursor.
• Gas Treatment: Used in amine scrubbing solutions for the removal of acidic gases like CO₂ and H₂S in natural gas processing and refining.

Quality Control

Our Hexamethyleneimine is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for industrial and fine chemical synthesis. Certificates of Analysis (COA) detailing purity, physical properties, and test results are provided with each shipment and are available upon request.

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 such as strong oxidizing agents and acids. Due to its highly volatile and hygroscopic nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
