Product Overview
English Name: HEPES, 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 membrane penetration rate 4. Low metal chelating ability 5. High chemical stability 6. Low absorption in ultraviolet and visible region
