Description

General Description

Acrylate-PEG-COOH (Acryl-PEG-COOH) is a versatile heterobifunctional PEG linker designed for polymer chemistry and biomedical research. The terminal acrylate group enables incorporation into polymer networks through radical polymerization, photopolymerization, and thiol-ene chemistry, while the carboxylic acid functionality provides a convenient handle for further derivatization and bioconjugation.

The hydrophilic PEG spacer improves water solubility, biocompatibility, and flexibility while reducing steric hindrance during coupling reactions. Acryl-PEG-COOH is frequently used in the preparation of hydrogels, surface coatings, drug delivery systems, tissue engineering scaffolds, and functional biomaterials.
