Leírás

Általános leírás

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.

Alkalmazás

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.
