Amine-PEG-amine (MW 5000)

• CAT Number: I045926
• Molecular Weight: 5000(Average)
• Purity: ≥95%

Amine-PEG-Amine (MW 5000)（Cat No.:I045926）is a linear polyethylene glycol derivative with a molecular weight of 5,000 Da, terminated with reactive primary amine groups at both ends. These amines readily form stable linkages with activated esters, carboxyl groups, and aldehydes, enabling versatile bioconjugation and crosslinking. The PEG spacer improves solubility, flexibility, and biocompatibility, while minimizing immunogenicity and nonspecific interactions. With its balanced chain length, this reagent is widely applied in hydrogel synthesis, surface modification, nanoparticle functionalization, and drug delivery systems that require stable and biocompatible PEG-based linkers.
