In the chemical materials system, long-chain fatty acid anhydrides, with their unique reactivity and compatibility, have become a key link connecting basic chemicals and high-end manufacturing. Among them, DDSA (Dodecenylsuccinic Anhydride, CAS No.: 26544-38-7), as a mixture of isomers, has achieved deep application in multiple fields such as epoxy resin processing, biomedicine, and petrochemicals due to its excellent crosslinking, modification, and curing properties, becoming one of the most competitive core products in the foreign trade chemical sector.

With 20 years of experience in the chemical trade, Henan Kebotuo Import & Export Co., Ltd. has always focused on the global supply chain layout of acid anhydride raw materials, deeply understanding the product characteristics and market demand pain points of DDSA. From a basic property perspective, DDSA has the molecular formula C₁₆H₂₆O₃, a molecular weight of 266.38, a liquid appearance, a density of 1.005 g/mL (25℃), a boiling point of 150℃/3 mmHg, and a refractive index of n₂₀/D of 1.479. It possesses good solubility and reaction stability, easily achieving esterification, amidation, and ring-opening reactions, thus meeting the processing needs of multiple scenarios.

As a multifunctional chemical raw material, DDSA's application scenarios cover multiple high-potential tracks, precisely matching the upgrading needs of the global high-end manufacturing and new materials industries:

1. Core Empowerment in the Curing Field of Epoxy Resins

DDSA is a high-quality hardener for thermosetting epoxy resins, widely used in paints, anti-corrosion coatings, adhesives, and circuit encapsulation. Its cured products possess both good toughness and corrosion resistance, significantly improving coating adhesion and circuit insulation performance, meeting the long-term protection needs of industrial equipment and electronic components, and enjoying stable demand in the automotive manufacturing and electronics industries .

2. Innovative Applications in Biomedicine and New Materials:

In the biomedical field, DDSA can be used as a precursor to synthesize modified chitosan hydrogels, enhancing the hydrophobicity of chitosan and enabling continuous local delivery of hydrophobic drugs, thus contributing to the upgrading of drug sustained-release technology. Simultaneously, it can also be used to prepare collagen hydrogel skin wound dressings, providing high-performance raw material support for the medical consumables field.

3. Diverse Applications in Petroleum and Environmental Protection:

Relying on its surface activity and anti-corrosion properties, DDSA can be used to prepare high-performance biosurfactants, suitable for oily sludge remediation and oil extraction operations, contributing to the green upgrading of the petrochemical industry. Furthermore, it can also be used as a rust inhibitor for turbine oil and hydraulic oil, and a solubilizer for metal cleaning agents, effectively improving the corrosion resistance of products and reducing equipment wear [6].

4. Other High-End Modification Scenarios:

As a highly efficient crosslinking agent, DDSA can be used for the modification and processing of various polymer materials, optimizing the mechanical properties and stability of materials. Simultaneously, it can be added to solvent-based adhesives to prevent corrosion of iron packaging by the adhesive, avoid discoloration of the adhesive, and improve product storage stability [6]. Against the backdrop of the global chemical industry's transformation towards green and high-end development, the market demand for DDSA continues to rise, especially in manufacturing-intensive regions such as Europe, America, and Southeast Asia, where it has become a core raw material for many enterprises. Henan Kebotuo, with its years of experience in domestic chemical trade and a mature foreign trade supply chain system, can provide high-quality DDSA products with a purity of over 90%, complete with compliant documents such as COA analysis certificates and certificates of origin, balancing product quality with international trade compliance requirements .
