Description

1,12-Diaminododecane is a linear aliphatic diamine with a twelve-carbon chain, serving as a versatile building block in polymer synthesis. Its bifunctional nature, featuring two primary amine groups, makes it a critical monomer for creating high-performance polyamides and other specialty polymers. This compound is essential for manufacturers in the polymer, coatings, and pharmaceutical intermediate industries seeking to produce materials with specific mechanical and thermal properties.

Application

• Polymer Synthesis: A key monomer for the production of nylon-12,12 and other long-chain polyamides, imparting flexibility, chemical resistance, and durability.
• Epoxy Curing Agent: Used as a curing agent for epoxy resins, contributing to improved toughness and flexibility in coatings, adhesives, and composites.
• Corrosion Inhibitor Intermediate: Serves as a precursor in the synthesis of corrosion inhibitors for industrial water treatment and metalworking fluids.
• Pharmaceutical Intermediate: Utilized in the synthesis of complex organic molecules and active pharmaceutical ingredients (APIs) requiring long-chain diamine structures.
• Surfactant and Dispersant Production: Acts as a raw material for manufacturing cationic surfactants and dispersing agents used in personal care and industrial formulations.
• Research & Development: Employed in academic and industrial R&D for developing novel materials, including dendrimers and organic frameworks.

Quality Control

Our 1,12-Diaminododecane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, color, and moisture content. We adhere to relevant industry standards and can provide material tailored to specific customer requirements, including research and commercial grades.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can lead to degradation. Keep away from strong acids and oxidizing agents.
