Description

3-[2-[2-[2-(2-Azidoethoxy)Ethoxy]Ethoxy]Ethoxy]Propanoic Acid Hydrazide is a specialized heterobifunctional crosslinking agent featuring a terminal azide group and a hydrazide moiety. This compound is engineered for efficient and selective bioconjugation, enabling the stable attachment of biomolecules, polymers, or other functional entities. It is primarily utilized by researchers and manufacturers in the fields of biopharmaceutical development, advanced material science, and diagnostic assay production.

Application

• Bioconjugation and Protein Labeling: Used to attach fluorophores, drugs, or other probes to antibodies, proteins, or peptides via the reactive hydrazide group, with the azide enabling subsequent "click chemistry" modifications.
• Polymer Functionalization: Serves as a key intermediate for introducing reactive handles into polyethylene glycol (PEG) derivatives and other polymeric scaffolds for drug delivery systems.
• Surface Immobilization: Facilitates the covalent attachment of biomolecules to azide-functionalized surfaces or nanoparticles for biosensor and microarray development.
• Chemical Biology Tool: Enables the study of biomolecular interactions and cellular processes through site-specific labeling strategies.
• ADC (Antibody-Drug Conjugate) Linker Precursor: Acts as a building block for constructing cleavable or non-cleavable linkers in targeted cancer therapeutics.
• Hydrogel Formation: Participates in cross-linking reactions to form biocompatible hydrogels for tissue engineering and 3D cell culture applications.
