Applications & Uses

Uses

Methyl Oxirane-2-carboxylate is an intermediate used in the synthesis of DL-Indole-3-lactic Acid-d5 (I627102), which is the isotope labelled analog of DL-Indole-3-lactic Acid (I627100); a reagent in the synthesis of 2-hydroxy-1-(1H-indol-3-yl)-4-methylpentan-3-one which has weak antibacterial activity against 16 bacterial strains, including Escherichia coli, Bacillus subtilis and Staphylococcus aureus. DL-Indole-3-lactic Acid is also used in the preparation of Monatin, a natural sweet peptidomimetic.
