11-Maleimidoundecanoic Acid is widely used in bioconjugation chemistry, particularly for linking biomolecules such as proteins, peptides, or antibodies to other entities like polymers, nanoparticles, or surfaces. The maleimide group reacts selectively with thiol groups (-SH) under mild conditions, making it valuable for creating stable thioether bonds. This property is exploited in the development of drug delivery systems, where it helps attach targeting ligands to drug carriers for improved specificity. It is also utilized in the preparation of biosensors, where biomolecules are immobilized onto sensor surfaces to enhance detection capabilities. Additionally, it plays a role in the synthesis of hydrogels and other biomaterials for tissue engineering and regenerative medicine applications. Its hydrophobic alkyl chain contributes to the stability and controlled release of conjugated compounds in various biomedical and industrial settings.
