PEG5-bis-(ethyl phosphonate)
This product is a symmetric PEG-based linker with two terminal ethyl phosphonate groups separated by a PEG5 spacer. The PEG chain enhances solubility and flexibility, while the phosphonates provide strong chelation and versatile reactivity for bioconjugation and material applications.
Key Features and Benefits:
-
Dual Ethyl Phosphonates: Enable strong chelation and surface binding.
-
PEG5 Spacer: Improves solubility, flexibility, and steric accessibility.
-
Symmetric Structure: Useful for balanced dual anchoring or crosslinking.
-
High Purity: Provides reproducibility in synthetic and bioconjugation workflows.
-
Versatile Design: Suitable for biomolecule modification and material functionalization.
Applications:
-
Bioconjugation: Links biomolecules through phosphonate–metal interactions or further derivatization.
-
Drug Delivery: PEGylated scaffold improves solubility and stability of therapeutic carriers.
-
Surface Functionalization: Anchors ligands to nanoparticles, hydrogels, or biosensors.
-
Material Science: Useful in coatings, polymers, and chelation systems.
Storage and Handling:
-
Storage: Store at –20 °C, tightly sealed and protected from light and moisture.
-
Handling: Use aqueous or anhydrous solvents depending on application requirements.
