I. [Product Description]
Desthiobiotin-PEG-SH is a high-purity organic intermediate that combines the specific binding ability of desthiobiotin with the steric hindrance effect of the PEG chain. It is suitable for the construction of bioconjugation systems. This compound enables precise and controllable coupling reactions through the thiol group (-SH) and can be used as a pharmaceutical intermediate or catalyst carrier, with significant application value in the fields of molecular recognition and surface modification.
