I. [Product Description]
Tosyl-DNP-PEG-NHS ester is a multifunctional organic intermediate that combines the directional modification ability of the tosyl group with the high-efficiency coupling characteristics of the NHS ester. Its core value lies in enhancing the molecular recognition ability through the DNP group and combining the excellent solubility of the PEG segment. It is particularly suitable for biomolecule labeling and functional material development, and shows unique advantages in the construction of catalytic systems and the design of nanocarriers.
