Acrylamide-PEG4-Carboxylic Acid (ACA-PEG4-COOH) is a PEG-based molecule featuring an acrylamide group on one end and a carboxylic acid on the other, with a PEG4 spacer in between. The PEG4 segment (four ethylene glycol units) makes it water-friendly and flexible, while the acrylamide end allows it to participate in polymerization or Michael addition reactions. The carboxylic acid terminus enables conjugation to amines or other functional groups (via EDC, NHS, etc.), making this molecule useful for building hydrogels, surface coatings, or bioconjugates.

Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
