Application

2-Amino-2-methyl-1-propanol can be used to study biological buffers. 2-Amino-2-methyl-1-propanol has been used in a study to report on an ATR-FTIR spectroscopic investigation of the CO(2) absorption characteristics of a series of heterocyclic diamines. 2-Amino-2-methyl-1-propanol has also been used in a study to develop a mild and convenient method for preparing 4,4-dimethyloxazoline (DMOX) derivatives of fatty acids for GC-MS analysis.
