Description

trans-1,3-Cyclohexanediamine is a versatile, chiral diamine building block with a rigid cyclohexane backbone, offering unique stereochemical and structural properties for advanced synthesis. Its value lies in its ability to act as a precursor for high-performance polymers, pharmaceuticals, and asymmetric catalysts, where its specific stereochemistry is critical for function. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds with enhanced activity or material properties.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in antiviral and central nervous system (CNS) drug candidates.
• Asymmetric Catalyst Ligand: Used to synthesize chiral ligands for transition metal catalysis, enabling enantioselective reactions in fine chemical production.
• Epoxy Curing Agent & Hardener: Imparts rigidity, thermal stability, and chemical resistance to epoxy resin systems in advanced composites and coatings.
• Polyamide & Polyurethane Synthesis: Serves as a monomer for creating specialty nylons and polyurethanes with improved mechanical strength and high-temperature performance.
• Agrochemical Synthesis: Intermediate in the production of herbicides, fungicides, and plant growth regulators with specific stereochemical requirements.
• Chelating Agent: Forms stable complexes with metal ions for applications in water treatment, metal extraction, and as additives in lubricants.

Quality Control

Our trans-1,3-Cyclohexanediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC and GC, to ensure it meets the high standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and absorption of moisture and carbon dioxide.
