Description

Apn-C3-Peg4-Azide is a heterobifunctional polyethylene glycol (PEG) crosslinker featuring an azide group and a terminal alkyne, designed for copper-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry. This compound is essential for creating stable, site-specific bioconjugates and modifying biomolecules, polymers, and surfaces with high efficiency and selectivity. It is primarily utilized by researchers and manufacturers in the fields of bioconjugation, pharmaceutical development, and advanced materials science.

Application

• Bioconjugation and antibody-drug conjugate (ADC) linker synthesis.
• Surface functionalization of nanoparticles and biomaterials for targeted delivery systems.
• Polymer modification and creation of PEGylated hydrogels for controlled release applications.
• Chemical biology research for labeling proteins, peptides, and oligonucleotides.
• Development of diagnostic assays and biosensors via immobilization strategies.
• Precursor in the synthesis of more complex multifunctional PEG derivatives.

Quality Control

Our Apn-C3-Peg4-Azide is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and mass spectrometry. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
