I. [Product Description]
COOH-PEG-NHS is a multifunctional organic intermediate. Its dual-reactive group design of carboxyl and succinimidyl ester (NHS) enables efficient bioconjugation under mild conditions. Thanks to the hydrophilicity and biocompatibility of the PEG chain, this compound is widely used in the modification of catalyst carriers and the synthesis of pharmaceutical intermediates. Customizable molecular weights are available to meet different experimental needs.

II. [Product Details]
