2-Deoxy-D-Glucose (2-DG) (CAS No. 154-17-6) is a synthetic glucose analog widely used in biochemical, pharmaceutical, and metabolic research. Structurally similar to D-glucose, 2-DG interferes with normal glucose metabolism, making it a valuable tool for studying glycolysis, cellular energy pathways, cancer metabolism, and viral replication mechanisms. Due to its ability to inhibit glucose utilization at the cellular level, 2-DG has attracted significant interest in oncology research, metabolic studies, and drug development.
