Dodecanedioic Acid (DDA), a linear saturated dicarboxylic acid with the chemical formula C12H22O4 and CAS 693-23-2, is a compound of significant industrial importance. Its unique C12 chain length and terminal carboxylic acid groups grant it a distinct set of chemical properties that are leveraged across various sectors, from polymer manufacturing to advanced lubricants. As a leading producer and supplier of specialty chemicals from China, we aim to illuminate the chemistry and industrial significance of DDA for B2B clients, including R&D scientists and procurement managers.

Chemical Structure and Properties

Dodecanedioic Acid is characterized by a twelve-carbon chain with carboxylic acid (-COOH) groups at each end. This structure gives it a relatively high molecular weight (230.304 g/mol) compared to shorter dicarboxylic acids. It typically presents as white powder or flake crystals, with a melting point around 127-129 °C. The key properties that make DDA industrially valuable include its excellent reactivity due to the two carboxylic acid groups, which readily undergo esterification and amidation reactions. These reactions are fundamental for producing polymers and esters. Its long aliphatic chain contributes to properties like flexibility, hydrophobicity, and good solubility in certain organic solvents, while its water solubility is pH-dependent.

Industrial Applications: A Versatile Building Block

The versatility of Dodecanedioic Acid is evident in its widespread applications. It is a critical monomer for synthesizing long-chain polyamides, notably Nylon 612, 1012, and 1212. These engineering plastics offer superior mechanical properties, heat resistance, and chemical stability, making them suitable for automotive parts, electrical components, and high-performance fibers. DDA is also a key intermediate in producing high-performance synthetic lubricants and greases, where its ester derivatives provide excellent thermal stability and lubricity. Furthermore, it finds use in coatings, adhesives, and as a raw material for certain fragrances. For manufacturers looking to buy Dodecanedioic Acid, these applications highlight its value as a foundational chemical intermediate.
