1,4:3,6-dianhydro-D-[UL-13C6]glucitol

1,4:3,6-dianhydro-D-[UL-13C6]glucitol (UL-13C6 DAG) is a rare and specialized chemical compound that has applications in both biomedical research and industrial manufacturing. UL-13C6 DAG is a derivative of D-glucitol (sorbitol) that has been isotopically labeled with six carbon-13 atoms, which makes it useful for stable isotope labeling experiments. This compound is commonly used as an internal standard in mass spectrometry-based metabolomics studies, where it is used to quantitatively measure the levels of other metabolites in biological samples. UL-13C6 DAG is also used in the production of high-performance plastics, resins, and adhesives. It is a key component in the synthesis of polycarbonates, which are widely used in the electronics, automotive, and construction industries. UL-13C6 DAG is a valuable precursor to other chemicals such as epoxides and cyclic carbonates. The chemical structure of UL-13C6 DAG consists of a six-membered ring with two anhydride groups attached to carbon atoms 1 and 4, and two hydroxyl groups attached to carbon atoms 3 and 6. The isotopic labeling of this molecule makes it a useful tool for studying metabolic pathways and chemical reactions. UL-13C6 DAG is a stable and non-toxic compound that can be safely handled and stored under normal laboratory conditions.
