Description

Acid-Peg6-Mono-Methyl Ester CAS NO 1807512-38-4 is a high-purity, functionalized polyethylene glycol derivative designed for advanced chemical synthesis and bioconjugation. This compound is valued for its role as a versatile linker and spacer, introducing hydrophilic PEG chains and a reactive acid group to modify the properties of target molecules. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise molecular engineering for drug delivery systems, diagnostic reagents, and specialty polymers.

Application

• Pharmaceutical Linker: Used in the synthesis of antibody-drug conjugates (ADCs) and peptide-drug conjugates to improve solubility and pharmacokinetics.
• Bioconjugation Reagent: Serves as a spacer arm for attaching dyes, probes, or proteins to surfaces or other biomolecules.
• Polymer Modification: Acts as a functional monomer or terminating agent to introduce carboxylic acid groups into PEG-based copolymers and hydrogels.
• Nanoparticle Functionalization: Employed to coat and stabilize nanoparticles, enhancing biocompatibility and providing a handle for further covalent attachment.
• Diagnostic Assay Development: Utilized in the preparation of labeled antigens or antibodies for immunoassays and biosensors.
• Surface Chemistry: Applied to create hydrophilic, non-fouling surfaces on medical devices or sensor chips.
