Description

n-Decylpropane-1,3-Diamine is a high-purity, linear aliphatic diamine featuring a long hydrocarbon chain. This bifunctional structure, containing both primary and secondary amine groups, makes it a versatile intermediate for synthesis and modification in demanding industrial applications. It is particularly valuable for manufacturers in the polymer, corrosion inhibitor, and specialty surfactant sectors seeking to enhance product performance through tailored chemical functionality.

Application

• Epoxy Curing Agent & Hardener: Imparts flexibility, chemical resistance, and improved adhesion in epoxy resin systems for coatings, composites, and adhesives.
• Corrosion Inhibitor Intermediate: Used in the synthesis of film-forming amines and other compounds that protect metal surfaces in industrial water treatment and oilfield applications.
• Polyamide & Polyurea Synthesis: Serves as a monomer or chain extender for producing specialty polymers with specific toughness, hydrophobicity, or reactivity profiles.
• Surfactant & Demulsifier Production: Acts as a key building block for creating cationic surfactants, emulsifiers, and oilfield demulsifiers due to its long alkyl chain and amine functionality.
• Chelating Agent & Metal Deactivator: Forms stable complexes with metal ions, useful in fuel and lubricant additives to prevent catalytic degradation.
• Pharmaceutical & Agrochemical Intermediate: Employed in the synthesis of active ingredients and fine chemicals requiring a specific hydrophobic diamine backbone.

Quality Control

Our n-Decylpropane-1,3-Diamine is produced under a stringent quality management system. Each batch is analyzed to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting results for assay, water content, and other critical parameters is provided with every shipment to guarantee consistency and traceability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
