Additional information

The hydrolysis of tert-butyl peroxyisobutyrate in different aqueous buffer solutions (pH = 4, 7 and 9) at 15, 37 and 50 °C was investigated using HPLC-UV. Measurements revealed a fast hydrolysis of tert-butyl peroxyisobutyrate. On the basis of retention times both potential hydrolysis products (tert-butyl hydroperoxide and isobutyric acid) were identified in stored buffer solutions at pH = 7 and pH = 9.
