PEG dialdehyde, Mp 3000

PEG dialdehyde (MW 3,000) features terminal aldehyde (-CHO) groups, allowing Schiff base formation with primary amines for crosslinking and conjugation. This highly water-soluble PEG derivative is widely used in hydrogel synthesis, bioadhesives, enzyme immobilization, and controlled drug delivery. The reactive aldehyde groups provide dynamic, reversible crosslinking for biomaterials and medical coatings.

Applications:
Biomolecule Conjugation: Enables site-specific immobilization of biomolecules for biosensors, biocatalysis, and diagnostics.
Biodegradable Hydrogels: Forms injectable, in situ-gelling hydrogels for wound healing, cell encapsulation, and tissue engineering.
Controlled Drug Release: Facilitates pH-sensitive drug carriers for responsive, localized release of therapeutics.
Bioadhesives: Used in medical-grade adhesives with strong, biocompatible bonding for tissue repair and wound closure.
Tissue Engineering: Supports the development of biomimetic scaffolds that promote cell attachment, proliferation, and differentiation.
