Description

Dodecanedioic Acid CAS NO 693-23-2 is a high-purity, long-chain dicarboxylic acid, also known as DDDA, valued for its excellent thermal stability and reactivity. This compound serves as a critical building block for high-performance polymers and specialty chemicals, offering superior properties compared to shorter-chain alternatives. It is essential for manufacturers in the nylon engineering plastics, powder coatings, lubricants, and pharmaceutical intermediates sectors seeking to enhance product durability and performance.

Application

• Nylon 6,12 and Other Polyamides: A key monomer for producing long-chain polyamides (e.g., Nylon 6,12) known for their low moisture absorption, excellent dimensional stability, and chemical resistance, used in automotive parts, electrical components, and industrial fibers.
• Powder Coatings and Polyester Resins: Used in the synthesis of saturated polyester resins, contributing to improved flexibility, weatherability, and flow properties in high-quality powder coatings for metal substrates.
• Synthetic Lubricants and Greases: Employed in the production of ester-based synthetic lubricants and complex greases that offer high thermal stability, low volatility, and excellent lubricity under extreme conditions.
• Plasticizers: Acts as a precursor for ester plasticizers, providing enhanced low-temperature flexibility and durability to PVC and other polymers.
• Pharmaceutical and Cosmetic Intermediates: Serves as a valuable intermediate in the synthesis of macrocyclic musk fragrances, drug delivery systems, and other fine chemicals.
• Adhesives and Sealants: Used to formulate high-performance polyurethane and other adhesives with improved adhesion and mechanical properties.
• Corrosion Inhibitors: Incorporated into formulations for metalworking fluids and industrial coatings as a corrosion-inhibiting additive.

Quality Control

Our Dodecanedioic Acid is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and melting point. Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability and compliance with your technical requirements. We can support compliance with standards relevant to your specific application, such as those for polymer or pharmaceutical intermediates.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
