About N-Hydroxy-5-norbornene-2,3-dicarboximide (HONB)

N-Hydroxy-5-norbornene-2,3-dicarboximide (HONB) is a highly efficient coupling reagent intermediate widely used in peptide synthesis and carbodiimide-mediated amide bond formation reactions. It enhances reaction efficiency and reduces racemization during peptide coupling processes.

HONB is commonly used in pharmaceutical research, peptide chemistry, and fine chemical manufacturing industries. It acts as an additive with carbodiimides like EDC to improve yield and minimize side reactions.

We supply high-purity HONB suitable for research and industrial-scale applications. Custom packaging and bulk quantities are available upon request.
