I. [Product Description]
Desthiobiotin-PEG-MAL is a multifunctional organic intermediate that combines the high-affinity binding properties of desthiobiotin with the efficient thiol coupling ability of maleimide groups. It is suitable for the modification of biomacromolecules and the functionalization of material surfaces. Its PEG chain can effectively improve water solubility and biocompatibility, and it is widely used in the preparation of pharmaceutical intermediates, the construction of catalytic reaction systems, and the synthesis of nanomaterials.
