I. [Product Introduction]
Tosyl-PEG-ISC (Tosyl-Polyethylene Glycol-Isocyanate) is a multifunctional organic intermediate. The tosyl and isocyanate groups endow it with high reactivity, making it suitable for bioconjugation, material modification, and catalytic reaction systems. The introduction of the PEG chain significantly enhances its water solubility and biocompatibility. It is a key raw material for the synthesis of pharmaceutical intermediates and the preparation of functional polymers.

II. [Product Details]
