This chemical is widely used in the field of bioconjugation and drug delivery systems. Its primary application involves modifying biomolecules, such as proteins, peptides, and nanoparticles, to enhance their solubility, stability, and biocompatibility. The carboxyl group (-COOH) allows for easy conjugation with amine-containing compounds, making it a valuable tool in creating targeted drug delivery systems. Additionally, it is utilized in the development of hydrogels and other biomaterials for tissue engineering and regenerative medicine. Its role in improving the pharmacokinetics and reducing immunogenicity of therapeutic agents makes it a critical component in advanced medical research and pharmaceutical formulations.
