Usage

Description

D-[2-13C]XYLOSE is a stable isotope-labeled analog of D-Xylose, a five-carbon sugar alcohol. It is specifically labeled with the stable isotope carbon-13 at the second carbon position, which makes it a useful compound for various applications in research and industry.

Uses

Used in Diagnostic Malabsorption Tests:
D-[2-13C]XYLOSE is used as a diagnostic tool for detecting and monitoring malabsorption issues in the human gastrointestinal tract. The application reason is that it can be easily traced and measured due to the presence of the stable isotope, allowing for accurate assessment of absorption capabilities.
Used in the Production of Furfural:
D-[2-13C]XYLOSE is used as a starting material for the synthesis of Furfural, an important industrial chemical used in the production of various resins, plastics, and other chemicals. The application reason is that the labeled xylose can be used to track the incorporation of the starting material into the final product, providing valuable insights into the synthesis process and potential optimization.

SYNTHESIS OF L-(4-2H)ERYTHROSE, L-(1-13C, 5-2H)ARABINOSE AND L-(2-13C, 5-2H)ARABINOSE AND IDENTIFICATION OF THE INTERMEDIATES BY 2H AND 13C-N.M.R. SPECTROSCOPY

L-(1-13C, 5-2H)Arabinose (6D) and L-(2-13C, 5-2H)arabinose (8D) have been synthesized by degradation of 2,3-O-isopropylidene-β-L-rhamnofuranose (2) to L-(4-2H)erythrose (5β, 5αD), with subsequent chain elongation to 6D plus L-(1-13C, 5-2H)ribose (7D), the latter being converted into 8D.Intermediates were identified by complete assignment of the 13C chemical shifts employing carbon-carbon and carbon-deuterium coupling constants, deuteration shifts, differential isotope-shifts, and deuterium spectra.The anomeric carbon atoms of 2 and 2,3-O-isopropylidene-L-(1-2H)erythrose (4D) gave only single 13C resonances, suggesting that these two compounds exists in only one major anomeric configuration, clarifying previously reported work.The synthesis of 2,3-O-isopropylidene-L-(1-2H)rhamnitol (3D) facilitated the assignment of the signals in the 13C spectra of the nondeuterated analog.Specific deuterium-enrichment and the observed carbon-deuterium coupling (1JC,D ca. 22 Hz) not only served to identify the deuterated carbon atom unambiguously in 3 but also permitted assignment of closely spaced resonances.The deuterium spectrum of 2,3-O-isopropylidene-L-(4-2H)erythrofuranose (4D) showed only a single resonance, indicating preponderance of one anomer, in accord with the observation of a single C-1 resonance in the 13C spectrum.
