BES-NA CAS 66992-27-6 CAS NO.66992-27-6

In biological experiments, it is an important PH stabilizing reagent. Generally, appropriate weak acid and its conjugate base are selected to mix to obtain appropriate PH value. Most biological reactions occur under neutral conditions, and PH is generally selected between 6-8, and the effective buffer range of buffer is also required to be between 6-8. In addition, the acid-base form of the buffer is required not to chelate with some metal ions.
