Hydroxybenzotriazole

Hydroxybenzotriazole (HOBT) is an organic compound used as a racemization suppressor and to improve yield in peptide synthesis. It is a white crystalline powder. Commercial HOBt always contains some water (~10% wt). One should not attempt to dry HOBt themselves however, as dry HOBt is explosive. Some of its uses can be read in the article about peptide synthesis
