General description

Acryloyl chloride is a derivative of acrylic acid and is widely used to introduce acrylic moieties into other compounds during organic synthesis. It can also be used as a precursor to synthesize acrylic monomers and polymers.

Application

Acryloyl chloride can be used as a precursor to synthesize:
  • Acrylamide-modified chitosan.
  • Ulvan acrylate macromer via esterification of hydroxyl groups of polysaccharides. This macromer can be used to prepare ulvan-based thermosensitive hydrogels.
  • Degradable peptide cross-linker by the acrylation of the amine groups of lysine residues and glutamine within peptide sequences.
