Used as a chiral building block in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its stereochemical purity makes it valuable in asymmetric synthesis and catalysis. Also employed in biochemical research to study metabolic pathways, especially those related to the citric acid cycle. Serves as a reference standard in analytical chemistry for the detection and quantification of isocitrate in biological samples. Compatible with enzymatic assays involving isocitrate dehydrogenase. Stable under physiological conditions, allowing its use in cell culture and metabolic studies.
