Description

Bocnh-Peg11-Ch2Ch2N3 (CAS NO 2395004-21-2) is a high-purity, heterobifunctional polyethylene glycol (PEG) linker featuring a Boc-protected amine at one terminus and an azide group at the other. This compound is essential for creating stable, water-soluble conjugates in advanced bioconjugation and materials science applications. It is specifically designed for researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors who require precise and reliable cross-linking agents for drug delivery systems, surface functionalization, and the synthesis of complex biomaterials.

Application

• Bioconjugation and ADC Development: Used as a key linker for attaching cytotoxic drugs to antibodies or proteins in Antibody-Drug Conjugate (ADC) research and production.
• PEGylation: Serves as a functionalized PEG spacer to improve the pharmacokinetic properties, solubility, and stability of therapeutic peptides and proteins.
• Click Chemistry: The azide terminus enables efficient, site-specific conjugation via copper-catalyzed or strain-promoted azide-alkyne cycloaddition (SPAAC) reactions.
• Surface Modification: Functionalizes nanoparticles, quantum dots, and other material surfaces for targeted drug delivery and diagnostic applications.
• Hydrogel and Biomaterial Synthesis: Acts as a cross-linking agent in the development of biocompatible hydrogels for tissue engineering and controlled release systems.
• Diagnostic Reagent Preparation: Utilized in the fabrication of biosensors and immunoassay components by linking recognition elements to signal reporters.
• Polymer Chemistry: A building block for synthesizing functionalized block copolymers with tailored properties.
