Description

Dnp-Peg6-Acid CAS NO 1817829-84-7 is a heterobifunctional polyethylene glycol (PEG) linker featuring a dinitrophenyl (DNP) group and a carboxylic acid terminus. This compound is essential for creating stable, cleavable conjugates in bioconjugation and drug delivery applications. It is primarily needed by researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic reagent industries for developing targeted therapeutics and advanced research tools.

Application

• Bioconjugation reagent for attaching peptides, proteins, or antibodies to various surfaces or carrier molecules.
• Key intermediate in the synthesis of antibody-drug conjugates (ADCs) and other targeted drug delivery systems.
• Functional linker in the development of cleavable, stimuli-responsive prodrugs and biomaterials.
• Tool compound for proteomics research, including affinity purification and pull-down assays.
• Building block for modifying nanoparticles or liposomes to enhance targeting and pharmacokinetic properties.
• Crosslinking agent in the preparation of hydrogels and polymer networks for controlled release.
