PIPES [piperazine-N,N′-bis(2-ethanesulfonic acid)] is frequently used as a buffering agent in biochemistry. It is an ethanesulfonic acid buffer developed by Good et al. in the 1960s. PIPES has a pKa near the physiological pH which makes it useful in cell culture work. It has been documented to minimize lipid loss when buffering glutaraldehyde histology in plant and animal tissues.

Molecular Formula:C8H16.5N2O6S2•1.5Na
Molecular Wt:335.34
Appearance:White crystalline powder
Assay≥99%
Enterprise Standard
Application: it is an important PH stable reagent in biotic experiments.
Appropriate PH is obtained by mixing mild acid and its conjugate base.
Many biological responses happen in neutral condition (usually PH 6-8),
so the buffering range is required to be in PH 6-8. In addition, the form
of acid-base of buffer should not chelate with some metallic ions.
Characteristics of biological buffer:
1, Strong water-solubility;
2. Compatibility of the acid-base dissociation balance;
3. Low membrance penetration rate;
4. Low metal chelating ability;
5. High chemical stability;
6. Low absorption in ultraviolet and visible region.
