About BES buffer, 99%

BES buffer (CAS 10191-18-1) is a biological buffer offered by Vaqora Chemicals (Biochemistry grade) with a typical assay of 99%. With the molecular formula C6H15NO5S, it has a molar mass of 213.25 g/mol. Systematically, it is named 2-[bis(2-hydroxyethyl)amino]ethanesulfonic acid. Common synonyms include N,N-Bis(2-hydroxyethyl)taurine and Taurine, N,N-bis(2-hydroxyethyl)-.

The material typically appears as a white powder or crystalline powder. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for buffer preparation, cell culture, electrophoresis and chromatography and diagnostic assays. Typical end-use sectors are academic and industrial research and diagnostics and biotechnology.

Vaqora Chemicals supplies BES buffer in 25 g, 100 g, 500 g and 1 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
