I. [Product Description]
PA-PEG-SH (Propionic acid-polyethylene glycol-thiol) is a multifunctional organic intermediate with both excellent reactivity and water solubility. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalytic systems. The thiol group (-SH) and carboxylic acid group (PA) in its molecule can achieve directional coupling and surface modification. The PEG segment endows it with good biocompatibility and adjustable molecular weight, making it an ideal choice for the preparation of nanomaterials and the development of functional polymers.

II. [Product Details]
