Introduction and application of BES buffer

BES buffer is a branch of the Good's buffering system, and like other Good's buffering agents, it belongs to the category of zwitterionic buffering agents. From the appearance, it appears in a white powder form, with a pure white color and a delicate powder texture. Its purity is very high, reaching a value of 99%. Due to its powder form, we need to configure it as a solvent before use. BES powder is soluble in water and easy to configure, with a buffering range between pH 6.4 and 7.8. Introduction to BES buffer: Chinese name: N, N-bis (2-hydroxyethyl) -2-aminoethanesulfonic acid English name: N, N-bis (2-hydroxyethyl) -2-aminoethanesulfonic acid acidCAS: 10191-18-1 Molecular formula: C6H15NO5S Molecular weight: 213.2 Grade: Biochemical grade Appearance: Pure white powder Purity: ≥ 99.0% PH (1% soluble in water, at 25 ℃): 2.5-5.0 Application of BES buffer: 1. In biological experiments, it is an important pH stabilizing reagent, usually selecting appropriate weak acids and their conjugated bases to mix to obtain a suitable pH value. 2. BES used as binding buffer and eluent in cation exchange chromatography 3. Used as buffer in gel filtration chromatography; 4. In personal care and cosmetic applications, BES, as a skin exfoliator, can protect active ingredients from degradation; 5. Used for water-based polyurethane materials; 6. A universal catalyst precursor for the mild hydrogenation carboxylation of alkanes to carboxylic acids.
