2-Hydroxypyridine N-Oxide (HOPO)

1-hydroxybenzotriazole hydrate (HOBt) has traditionally been used in amide coupling reactions to suppress side reactions and minimise racemisation, the latter challenge being a key one in peptide synthesis. A recent change in the UN classification of HOBt has resulted in restrictive shipping regulations for this product and has stimulated interest in the lesser known alternative, 2-hydroxypyridine-n-oxide.
