PEG2-bis(phosphonic acid)
This symmetric PEG2 linker has two terminal phosphonic acids that provide strong chelation and versatile reactivity. The PEG2 spacer enhances hydrophilicity and solubility, making it valuable for bioconjugation, material science, and biomedical applications.
Key Features and Benefits:
-
Dual Phosphonic Acids: Provide strong chelation with metals and stable surface binding.
-
PEG2 Spacer: Adds hydrophilicity, solubility, and reduced steric hindrance.
-
Symmetric Structure: Enables dual anchoring or crosslinking strategies.
-
High Purity: Ensures reproducibility in sensitive workflows.
-
Versatile Design: Suitable for biomolecule modification and material functionalization.
Applications:
-
Surface Functionalization: Anchors biomolecules to metal oxides, nanoparticles, or biosensor platforms.
-
Bioconjugation: Serves as a hydrophilic spacer with dual reactive phosphonic groups.
-
Drug Delivery: Supports PEGylated drug carriers and targeted delivery scaffolds.
-
Material Science: Useful for coatings, chelators, and polymer modification.
Storage and Handling:
-
Storage: Store at –20 °C in a tightly sealed, light-protected container.
-
Handling: Use aqueous or anhydrous solvents depending on application needs.
This product combines strong chelation with hydrophilic PEG spacing, making it an especially excellent reagent for bioconjugation, surface chemistry, and advanced material design.
