Description

Ald-Peg3-Azide CAS NO 1002342-83-7 is a heterobifunctional polyethylene glycol (PEG) crosslinker featuring an aldehyde group and a terminal azide, designed for precise bioconjugation and click chemistry applications. This compound is essential for creating stable, site-specific linkages between biomolecules, enabling advanced research and development in life sciences. It is a critical reagent for scientists and manufacturers in the fields of biopharmaceuticals, proteomics, and advanced materials development.

Application

• Bioconjugation and Protein Modification: Site-specific labeling of antibodies, enzymes, and other proteins via the aldehyde group for reaction with amines or hydrazides.
• Click Chemistry Synthesis: Utilizes the azide group for copper-catalyzed azide-alkyne cycloaddition (CuAAC) to create PEGylated small molecules, polymers, or surfaces.
• ADC (Antibody-Drug Conjugate) Development: Serves as a versatile linker for constructing homogeneous ADCs by connecting cytotoxic payloads to monoclonal antibodies.
• PEGylation Reagent: Introduces a hydrophilic, flexible PEG spacer to enhance the solubility, stability, and pharmacokinetic properties of therapeutic compounds.
• Surface Functionalization: Immobilization of biomolecules onto chips, nanoparticles, or other solid supports for biosensor and diagnostic assay development.
• Material Science: Building block for synthesizing functional hydrogels, smart polymers, and biocompatible materials with tailored properties.
