PEG3-bis(phosphonic acid)
This product is a symmetric linker with two terminal phosphonic acid groups separated specifically by a PEG3 spacer. The PEG chain enhances solubility and flexibility, while the phosphonate groups provide strong chelation and reactivity, making it highly useful in bioconjugation, drug delivery, and material science.
Key Features and Benefits:
-
Dual Phosphonic Acids: Offer strong chelating ability and versatile reactivity.
-
PEG3 Spacer: Improves solubility, hydrophilicity, and steric accessibility.
-
Symmetric Design: Supports balanced dual anchoring or crosslinking.
-
High Purity: Ensures reproducibility in sensitive workflows.
-
Versatile Use: Suitable for biomolecule modification, coatings, and advanced scaffolds.
Applications:
-
Bioconjugation: Links biomolecules via phosphonate–metal interactions.
-
Drug Delivery: PEGylated scaffold improves solubility and stability of therapeutic systems.
-
Surface Functionalization: Anchors ligands to nanoparticles, polymers, and biosensors.
-
Material Science: Useful in polymer engineering, coatings, and chelation systems.
Storage and Handling:
-
Storage: Store at –20 °C in a sealed, moisture-protected container.
-
Handling: Use aqueous or anhydrous solvents as appropriate; avoid prolonged exposure to high humidity.
This product combines strong phosphonate reactivity with PEG hydrophilicity, making it an especially versatile tool for conjugation, drug delivery, and advanced material design.
