Description

1,12-Dodecanediamine is a linear aliphatic diamine with a 12-carbon chain, serving as a versatile building block for high-performance polymers and specialty chemicals. Its bifunctional nature, featuring two primary amine groups, makes it a critical monomer for creating polyamides (nylon 12,12) with excellent mechanical strength, chemical resistance, and thermal stability. This compound is essential for manufacturers in the polymer, coatings, and adhesives industries seeking to develop durable materials for automotive, electronics, and industrial applications.

Application

• Polymer Synthesis: A key monomer for the production of long-chain polyamides (e.g., Nylon 12,12), offering superior flexibility, hydrolytic stability, and low moisture absorption compared to shorter-chain nylons.
• Epoxy Curing Agent: Used as a curing agent for epoxy resins, contributing to improved toughness, chemical resistance, and thermal properties in coatings, adhesives, and composite materials.
• Corrosion Inhibitors: Employed in the formulation of corrosion inhibitors for metal treatment processes and fuel additives.
• Surfactants and Lubricants: Acts as an intermediate in the synthesis of cationic surfactants, emulsifiers, and specialty lubricants.
• Pharmaceutical & Agrochemical Intermediates: Serves as a valuable building block in the synthesis of active pharmaceutical ingredients (APIs) and agrochemicals.
• Organic Synthesis: Utilized as a linker or spacer molecule in organic synthesis and for the preparation of metal-chelating agents.

Quality Control

Our 1,12-Dodecanediamine is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to relevant industry standards and can support compliance requirements for various applications.

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 oxidizers and acids.
