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.

For better dissolution, please heat the test tube at 37°C and shake it in an ultrasonic bath for a while. The solubility of different batches of products from different manufacturers are different, which is only for reference. If the concentration required for the experiment is too large to the product solubility limit, please add a co-solvent or adjust the concentration by yourself.
