I. [Product Description]
SH-PEG-Niacin (Mercapto-Polyethylene Glycol-Nicotinic Acid) is a multifunctional organic intermediate with the characteristics of both pharmaceutical intermediates and polymer material modifiers. Its mercapto and carboxylic acid groups can achieve precise coupling through click chemical reactions. The PEG chain significantly enhances water solubility and biocompatibility, making it suitable for the construction of catalyst carriers and functional surface engineering.
