Application

2-Amino-2-methyl-1,3-propanediol can be used to study biological buffers. 2-Amino-2-methyl-1,3-propanediol has been used in a study to afford a new family of isostructural octanuclear Cu4Ln4 complexes. 2-Amino-2-methyl-1,3-propanediol has also been used in a study to improve cooling refrigerants for low-temperature applications.
Buffer component in a SDS-gradient gel electrophoresis system that separates polypeptides in the molecular weight range of 1500 to 100,000. Used as a spacer in isotachophoresis of proteins. Also used as a buffer for the determination of alkaline phosphatase activity.

Formation constants of the silver(I) complexes with some amino-alcohols have been determined at 25 degrees C in 0.5 M KNO(3) by means of two independent potentiometric measurements employing glass and silver electrode. The ligands considered are: sec-butylamine, 2-amino-1-propanol, 2-amino-1-methoxy-propane, 2-amino-2-methyl-1-propanol

The inhibitory effect of inorganic phosphate on the activity determination of isoenzymes of alkaline phosphatase (AP) in diethanolamine (DEA), glycine and 2-amino-2-methyl-1,3-propandiol (AMPD) buffer was studied. This effect depends on the buffer used and isoenzyme investigated. Especially the placental isoenzyme
