General Description

HOAt spot supply | 1-Hydroxy-7-azabenzotriazole CAS:39968-33-7

HOAt (39968-33-7) can inhibit the generation of racemization in peptide condensation; also used for fragment condensation.Compared with the similar DIC/HOBt system in DMF and DCM, the DIC/ HOAt system can more effectively retain the structure for peptide coupling .HOAt is a new type of high-efficiency condensation reagent used in peptide synthesis.
