| Product Name | POPSO sesquisodium salt biological buffer, CAS 108321-08-0, pKa 7.8 |
| Catalog No. | ATR-B-YJL-0266 |
| Description | POPSO sesquisodium salt, chemically known as piperazine-N,N'-bis(2-hydroxypropanesulfonic acid) sesquisodium salt, is a derivative of POPSO and serves as a biological buffer. Although its applicable range is narrower than that of POPSO itself, the sesquisodium salt form remains irreplaceable in certain application scenarios. It has a pKa of 7.8 at 25 °C and an acid-base indicator transition range of pH 7.2-8.5, making it suitable for buffering in the near-neutral to slightly alkaline region. |
| Intended Use | Used as a biological buffer in biochemical and life science research where stable pH control in the near-neutral range is required. |
| Storage Conditions | Store at room temperature. |
| Package Specifications | 25 kg/drum |
| Purity | >99% |
| Molecular Weight | 386.41 |
| pH Range / Optimal pH | Indicator transition range pH 7.2-8.5; pKa 7.8 (at 25 °C) |
