Description

α-L-Arabinopyranose(9Ci) is a specific stereoisomer of the pentose sugar arabinose. This high-purity monosaccharide is a critical building block and chiral intermediate in advanced organic synthesis and biochemical research. It is essential for industries requiring precise carbohydrate chemistry, such as pharmaceutical development, where it serves as a precursor for nucleoside analogs and complex glycoconjugates. Its defined stereochemistry makes it a valuable reagent for studying enzyme mechanisms and synthesizing specialized biomolecules.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of antiviral and anticancer nucleoside analogs.
• Glycochemistry Research: Used as a chiral precursor for constructing complex oligosaccharides, glycopeptides, and glycolipids.
• Biochemical Standard: Serves as a reference standard in analytical methods like HPLC and GC for sugar analysis and metabolic studies.
• Enzymology Studies: Employed as a substrate to investigate the specificity and mechanism of glycosidases and glycosyltransferases.
• Food & Flavor Science: Potential use in research related to Maillard reaction products and the development of novel flavor compounds.
• Cosmetic Ingredient Research: Investigated for applications in moisturizing agents and skin-conditioning formulations due to its humectant properties.

Quality Control

Our α-L-Arabinopyranose is produced under a strict quality management system. Each batch is subjected to comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, which includes data from tests such as HPLC assay, optical rotation, and residual solvent analysis. Our quality commitment supports applications in regulated environments, including pharmaceutical R&D.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
