AI Overview
8-arm Poly(ethylene glycol) amine with a tripentaerythritol (TP) core, 8-arm PEG-NH2(TP), is a high-purity, branched PEG derivative used for crosslinking, drug delivery, and hydrogel formation. Featuring a TP core rather than hexaglycerin, it offers lower polydispersity and improved molecular weight precision, usually in HCl salt form.
Key Features and Applications
- Structure: Eight amine () terminated arms extending from a central tripentaerythritol core.
- Reactivity: High reactivity with carboxyl groups (-COOH), NHS esters, and other amine-reactive groups for bioconjugation.
- Molecular Weights: Common Mn (number average molecular weight) ranges include 10K, 20K, and 40K Da.
- Applications: Ideal for creating hydrogels, surface functionalization, and drug delivery systems.
- Storage: Store at in a dry environment.
