SHB (Succinimidyl-4-Hydroxybenzoate) is a classic NHS active ester coupling reagent, widely applied in biomolecule labeling, protein crosslinking, bioconjugation experiments and pharmaceutical intermediate synthesis.

Its succinimide ester group can form stable amide bonds with primary amino groups of proteins, peptides and antibodies, realizing directional modification of biomolecules without destroying the natural biological activity of target molecules. Our SHB adopts refined synthesis process, purity reaches ≥99%, low impurity content, stable batch quality, fully meets laboratory research and pharmaceutical production standards.
