Properties:
Phosphorylated Chitosan (PCH) is a modified form of chitosan that exhibits enhanced solubility following phosphorylation. While retaining the inherent biocompatibility of chitosan, it significantly boosts capabilities for metal ion chelation, antimicrobial activity (particularly against Gram-positive bacteria), and antioxidant defense.
As a pivotal precursor material, phosphorylated chitosan finds application in bone tissue engineering (specifically in the formation of biomimetic apatite), hemostatic agents, carriers for sustained drug release, and industrial wastewater treatment.
Package and Storage:
25KG/bag. Store in a cool, dry, well-ventilated area. Keep away from moisture and strong oxidizing agents.
