Description

β-L-Arabinopyranose Tetraacetate is a high-purity, fully acetylated derivative of the pentose sugar L-arabinose. This compound serves as a crucial protected intermediate in synthetic organic chemistry, particularly in carbohydrate and nucleoside synthesis, where it provides regioselective control. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries developing novel active ingredients and complex biomolecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of nucleoside analogs, antiviral agents, and other bioactive molecules.
• Carbohydrate Chemistry: Used as a protected glycosyl donor or acceptor in the stereoselective synthesis of oligosaccharides and glycoconjugates.
• Fine Chemical Synthesis: Intermediate in the production of chiral ligands, catalysts, and specialty chemicals requiring defined sugar scaffolds.
• Agrochemical Research: Serves as a precursor for developing novel sugar-based pesticides or plant growth regulators.
• Biochemical Research: Tool compound for studying enzyme mechanisms, such as glycosidases and glycosyltransferases.
• Material Science: Potential monomer for creating biodegradable polymers or functionalized surfaces with specific carbohydrate motifs.

Quality Control

Our β-L-Arabinopyranose Tetraacetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and specific tests for residual solvents and moisture. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 use to prevent moisture absorption, which may affect product stability and performance.
