Description

D-Xylose-1,2,3,4,5,5'-C-D6 is a stable isotope-labeled analog of D-xylose, where six carbon atoms are replaced with the non-radioactive isotope carbon-13 (C-13). This high-purity labeled compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, biotechnology, and nutritional science sectors for applications requiring exceptional accuracy and reliability in mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Quantitative Analysis: Used in LC-MS and GC-MS for the accurate quantification of D-xylose and related metabolites in complex biological matrices.
• Metabolic Flux Analysis (MFA): Enables the detailed tracing and modeling of pentose phosphate pathway and carbohydrate metabolism in cellular systems.
• Pharmaceutical Research: Serves as a critical tool in drug metabolism and pharmacokinetics (DMPK) studies for investigating the absorption and metabolism of sugar-based therapeutics.
• Nutritional Science Studies: Applied in research on carbohydrate digestion, gut microbiome function, and malabsorption disorders.
• Biochemical Assay Development: Used to validate and calibrate enzymatic assays for xylose and xylulose.
• Stable Isotope Labeling in Biomolecule Synthesis: Acts as a building block for the synthesis of labeled oligosaccharides, glycoconjugates, or other biomolecules for structural studies.
