Used as an intermediate in the synthesis of aspartame, a low-calorie artificial sweetener. It plays a key role in the enzymatic or chemical conversion processes that lead to the formation of aspartame’s dipeptide structure. Due to its chiral properties, it allows for the production of both D- and L-isomers of aspartic acid derivatives, which is important in controlling the purity and efficiency of the final sweetener product. Also investigated in biochemical research for its role in mimicking metabolic intermediates in amino acid pathways.
