The chemical name of HEPES is 4-hydroxyethylpiperazineethanesulfonic acid (CAS: 7365-45-9), a white crystalline powder. The pH buffer range is 6.8~8.2 and has a pKa of 7.5 at 25°C. In biological experiments, it is an important pH stabilizing agent, usually by selecting an appropriate weak acid and its conjugate base to give a suitable pH. Most biological reactions occur under neutral conditions, and the acid-base form of the buffer is not required to chelate with certain metal ions.
