MES Sodium Salt (CAS 71119-23-8) is the sodium salt of MES, a classic Good's buffer widely used in life science research and biopharmaceutical manufacturing. It provides stable buffering capacity at pH 5.5--6.7 with a pKa of 5.96 at 25°C. MES-Na is highly water soluble, low in UV absorption (max <260 nm), and non-toxic to cell lines, making it ideal for cell culture, protein purification, electrophoresis, and diagnostic reagents. Our product is ≥99% purity, strictly quality controlled, and supplied with COA, MSDS, and TDS.
