I. [Product Description] 
Mal-PEG-Dansyl is a multifunctional organic intermediate. Through the efficient coupling of maleimide groups with thiol groups and the fluorescence properties of dansyl chloride, it is widely used in the fields of biological labeling and material modification. Its core value lies in the adjustable molecular weight design of the polyethylene glycol (PEG) chain, which can optimize solubility and steric hindrance, and is suitable for the synthesis of pharmaceutical intermediates and the construction of catalytic reaction systems.
