Detailed Description
English Name: N,N-Bis(2-Hydroxyethyl)-2-aminoethanesulfonic acid Molecular Formula:C6H15NO5S Molecular Wt:213.2 Appearance:White crystalline power Assay(by Titn,dried basis):101.1% 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.
