Description

β-Xylopyranose (9Ci) is a specific stereoisomer of the pentose sugar xylose, characterized by its β-configured pyranose ring structure. This compound is a fundamental building block and a key reference standard in carbohydrate chemistry research and analytical method development. It is essential for scientists and manufacturers in the pharmaceutical, biotechnology, and food science industries who require high-purity monosaccharides for synthesis, metabolic studies, and quality control.

Application

• Pharmaceutical Reference Standard: Used as a high-purity analytical standard for the identification and quantification of xylose and related carbohydrates in drug substances and excipients.
• Biochemical Research: Serves as a critical substrate or intermediate in enzymatic studies, metabolic pathway analysis, and glycoscience research.
• Glycoconjugate Synthesis: Acts as a starting material or protected intermediate for the chemical and enzymatic synthesis of oligosaccharides, glycopeptides, and other complex biomolecules.
• Food & Beverage Analysis: Employed in analytical methods to measure xylose content, monitor fermentation processes, or assess product authenticity.
• Cosmetic Science: Investigated for potential applications in moisturizing agents or skin-conditioning formulations derived from natural sugars.
• Industrial Biotechnology: Used in research focused on the microbial conversion of hemicellulose (xylan) into value-added chemicals and biofuels.
