Dodecenylsuccinic acid

Dodecenylsuccinic acid (CAS 29658-97-7) is a long-chain alkenyl dicarboxylic acid.

Where is Dodecenylsuccinic acid used?

• Metalworking and industrial lubricants: corrosion inhibitor that adsorbs onto metal surfaces, forming a protective barrier against rust and oxidation
• Coatings: reactive building block in alkyd and epoxy systems, where the pendant chain contributes flexibility and the diacid groups participate in crosslinking and curing
• Adhesives and sealants: improves substrate adhesion and modifies the mechanical profile of the cured system
• Polymer production: monomer or plasticizer precursor in polyester and polyamide synthesis, with the dodecenyl chain imparting internal softening without a separate additive
• Its bifunctional acid structure enables it to act as a corrosion inhibitor.

Commercial specifications

• Purity specifications commonly confirmed by acid value and saponification value
• Packaging in drums and IBC containers suited to industrial procurement volumes
