Molecular Formula:C4H*1NO3 Molecular Wt:**1.*4 CASï&frac*4;******1 Appearance:White crystalline powder Assay:*9.*8ï&frac*4; Enterprise Standard Application: it is an important PH stable reagent in biotic experiments. Appropriate PH is obtained by mixing mild acid and its conjugate ***** biological responses happen in neutral condition (usually PH **8), so the buffering range is required to be in PH **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.
