1. [Product Description]
HS-PEG-STA is a multifunctional organic intermediate. Through the high reactivity of the mercapto group (-SH), the hydrophilicity of polyethylene glycol (PEG), and the hydrophobicity of stearic acid (STA), precise molecular design can be achieved. It is widely used in the synthesis of pharmaceutical intermediates and catalyst support systems. Its unique amphiphilic structure can effectively regulate the interfacial properties of materials, providing an efficient solution for functional modification.
