Biological Buffers


Synonym: β-Aminoisobutyl alcohol, 2-Amino-2-methyl-1-propanol  

Determination of alkaline phosphatase, lactate dehydrogenase and malate dehydrogenase4,5 Used as a choline biosynthesis inhibitor8. Used to determine the activity of chymase in a composite buffer system9. Stabilizes the Calmagite reagent in the automated measurement of magnesium in serum and urine6. Used in an efficient synthesis of 2-oxazolidinones via carbonylation with CO in the presence of salen-cobalt catalysts. Used to derivatize carboxylic acids for GC analysis1 and to synthesize 2-oxazolines2 for further transformations3.
Useful pH Range 9.0 - 10.5

Interaction Comments

AMP has a low melting point (18 - 26°C) and has to be liquified at approx. 35°C to prepare a buffer solution. The liquified AMP has a high viscosity, which makes its handling more difficult4.
If this buffer solution is stored at room temperature and protected from the CO2 from the air, it is stable for approx. one month4.
Slight interaction with Ni, Cu, Zn, Cd and Pb7
