Description

D-[2-13C]Xylose is a stable isotope-labeled analog of the pentose sugar D-xylose, specifically enriched with carbon-13 at the C-2 position. This compound is essential as a precise tracer in metabolic flux analysis and nuclear magnetic resonance (NMR) spectroscopy studies, enabling researchers to track biochemical pathways with high accuracy. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on carbohydrate metabolism, glycobiology, and the development of novel diagnostic agents.

Application

• Metabolic Pathway Tracing: Used as a 13C-labeled tracer in in vitro and in vivo studies to elucidate pentose phosphate pathway and glycosylation mechanisms.
• NMR Spectroscopy: Serves as an internal standard and probe for structural analysis and quantification in complex biological matrices.
• Pharmaceutical Research: Critical in the development and testing of drugs targeting metabolic disorders and in pharmacokinetic studies.
• Biochemical Assays: Employed in enzyme activity assays and studies of carbohydrate-active enzymes.
• Nutritional Science Research: Used to investigate the metabolism of dietary sugars and fibers.
• Isotope Dilution Mass Spectrometry (IDMS): Acts as a high-purity standard for accurate quantification in mass spectrometry-based methods.
