Description

3-O,4-O,5-o-Trimethyl-D-Xylose is a selectively protected derivative of the pentose sugar D-xylose. This compound is a crucial chiral intermediate and building block in organic synthesis, offering a protected scaffold for the controlled introduction of further functional groups. It is primarily utilized by research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and fine chemical sectors for the development of novel active ingredients and complex carbohydrate-based molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon for the synthesis of nucleoside analogs, antiviral agents, and other bioactive molecules.
• Glycochemistry Research: Used as a protected starting material for the construction of oligosaccharides, glycoconjugates, and carbohydrate libraries.
• Agrochemical Synthesis: Acts as a building block for developing novel herbicides, insecticides, or plant growth regulators with specific stereochemistry.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, and fragrances requiring precise sugar modifications.
• Academic & Industrial R&D: A valuable tool for methodological development in synthetic organic chemistry and catalysis studies.

Quality Control

Our 3-O,4-O,5-o-Trimethyl-D-Xylose is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed specifications are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage at 2-8°C.
