Description

7-Diethylaminoheptylamine is a versatile aliphatic diamine intermediate featuring a long hydrocarbon chain terminated with a diethylamino group. This unique bifunctional structure makes it a valuable building block for synthesizing specialized surfactants, corrosion inhibitors, and pharmaceutical intermediates. It is particularly sought after by manufacturers in the agrochemical, personal care, and specialty polymer industries for creating performance-enhancing additives and active ingredients.

Application

• Surfactant and Emulsifier Synthesis: Acts as a key intermediate for producing cationic and amphoteric surfactants used in fabric softeners, hair conditioners, and industrial cleaners.
• Corrosion Inhibitor Formulation: Utilized in the development of film-forming amine-based corrosion inhibitors for industrial water treatment and oilfield applications.
• Pharmaceutical Intermediate: Serves as a precursor in the synthesis of active pharmaceutical ingredients (APIs) and quaternary ammonium compounds with biological activity.
• Epoxy Curing Agent & Hardener: Functions as a curing agent for epoxy resins, imparting flexibility and improved chemical resistance to the final polymer.
• Agrochemical Additive: Used in the production of herbicides, pesticides, and plant growth regulators as an intermediate or formulation aid.
• Polymer Modification: Incorporated into polyamide or polyurethane chains to modify physical properties like solubility, flexibility, and adhesion.
• Gas Treating Agent: Employed in the formulation of solvents for acid gas (CO₂, H₂S) removal in natural gas processing.
• Research & Development: Serves as a valuable reagent in organic synthesis and chemical research for creating novel amine-functionalized compounds.

Quality Control

Our 7-Diethylaminoheptylamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC or HPLC for assay and purity, to ensure it meets exacting specifications for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

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 nature, the container must be kept tightly sealed to exclude moisture. Keep away from heat, sparks, open flames, and strong oxidizing agents.
