English Name:N-(2-acetamido)iminodiacetic acid
Molecular Formula:C6H10N2O5
Molecular Wt:190.2
Appearance:white power
Assay,%(Titration):99.7%
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.
