HOBT (1-Hydroxybenzotriazole) is a common amide condensing agent, which forms amide from organic acid and amine.The structure of HOBt is a benzotriazole structure, so it is water-soluble but not high, that is, slightly soluble. Generally, the reaction process does not use aqueous phase, and generally uses non-aqueous solvents, such as tetrahydrofuran and dichloromethane.
Because HOBt has triazole structure, it can be dissolved in inorganic acid aqueous solution. In addition to formic acid and acetic acid, organic acids can also be used as solvents. Most other organic acids are solid at room temperature and are generally not solvents.HOBT peptide condensers are widely used in peptide condensation reactions with carbodiimide condensers, which can significantly reduce the racemization ratio and prevent racemization during peptide fragment condensation.
