Used extensively in research involving isotopic labeling, particularly in NMR spectroscopy to study molecular structures and dynamics. It plays a crucial role in metabolic pathway analysis, helping to trace and understand biochemical processes in living organisms. In pharmaceutical development, it aids in the investigation of enzyme mechanisms and drug interactions, providing insights that are critical for the design of new therapeutic agents. Additionally, it is employed in the synthesis of isotopically labeled peptides and proteins, facilitating advanced studies in proteomics and molecular biology.
