Merck, 443271-1L, Dodecenylsuccinic anhydride, mixture of isomers

General description
Dodecenylsuccinicanhydride (DDSA) is a mixture of isomers that belongs to the class of long-chained aliphatic anhydrides. It is composed of a dodecenyl (C12) chain attached to a succinic acid backbone and can undergo esterification, amidation, and ring-openingreactions. It is widely used as a cross-linking agent to synthesize hydrogels for drug delivery, coating for medical devices, and as a hardener for curing epoxy resins.
Application
Dodecenylsuccinic anhydride, mixture of isomers can be used:

As a precursor to synthesize modified chitosan hydrogels useful for the sustained local delivery of drugs. This modification enhances the hydrophobicity of chitosan, allowing it to better encapsulate and retain hydrophobic drugs.
To prepare high-performance Arabinoglucuronoxylan (AGX)-based biosurfactants using rapid homogeneous esterification reactions. These surfactants can be used for oily sludge remediation and oil recovery.
As a hardener for curing thermosetting epoxy resins used in various fields such as paints, corrosion protective coatings, adhesives, and electrical circuits.
As a modifying agent to prepare collagen hydrogels to fabricate skin wound dressings.
