HEPES CAS:7365-45-9 English Name:4-(2-hydroxyerhyl)piperazine-1-erhanesulfonic acid Molecular Formula:C8H18N2O4S Molecular Wt:238.31 Appearance:Free flowing white powder Assay(potertiometric cal on dry substance):99.8%. 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. Packing:25KG / DRUM.
