Description

N,N''-Dimethyl-1,12-Diaminododecane is a high-purity, long-chain aliphatic diamine derivative with terminal dimethylamino groups. This compound serves as a versatile and effective intermediate for the synthesis of specialized polymers, surfactants, and corrosion inhibitors. It is particularly valuable for manufacturers in the polymer, coatings, and specialty chemicals industries seeking to develop products with enhanced flexibility, adhesion, or cationic functionality.

Application

• Polymer & Resin Intermediate: A key monomer for the production of polyamides, polyurethanes, and epoxy curing agents, imparting flexibility and improved mechanical properties.
• Corrosion Inhibitor Formulation: Used in the synthesis of cationic surfactants and filming amines that protect metal surfaces in industrial water treatment and oilfield applications.
• Surfactant & Emulsifier Synthesis: Acts as a precursor for quaternary ammonium compounds (quats) used in fabric softeners, hair conditioners, and industrial emulsifiers.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and agrochemicals requiring long-chain diamine backbones.
• Epoxy Hardener Component: Functions as a co-hardener or modifier in epoxy resin systems to adjust curing speed, crosslink density, and final toughness.
• Textile & Leather Auxiliary Chemicals: Used in the manufacture of softening agents, dye-fixing agents, and other functional auxiliaries for the textile and leather industries.

Quality Control

Our N,N''-Dimethyl-1,12-Diaminododecane is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC, identity confirmation (IR, NMR), and impurity profiling to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting all critical specifications are available upon request to support your quality assurance and regulatory needs.

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 affect product quality.
