Description

Application

DL-Leucine is a racemic mixture of the D- and L- enantiomers of Leucine. DL-Leucine is used to form benzimidazole and pyrimidine hydroxy azo dyes with various transition metals. DL-Leucine may be used for the evaluation of chiral amino acid separation techniques.

DL-Leucine is used for the following applications:

• Used as a standard for the measurement of free amino acids
• Used in the process of tritiated leucine uptake
• Used in solution preparation (various organics were used in different combinations and concentrations to model complex surface tension effects, DL-Leucine is one of them). It is chosen due to its presence in atmospheric aerosols and ice nucleation activity as well as for its surfactant character
