Description

A-D-Maltose Octaacetate is a fully acetylated derivative of the disaccharide maltose, serving as a crucial protected intermediate in synthetic carbohydrate chemistry. Its primary value lies in providing a stable, non-reactive scaffold that allows for selective deprotection and further functionalization at specific hydroxyl sites. This compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-purity building blocks for oligosaccharide synthesis, glycosylation studies, and the development of novel bioactive molecules.

Application

• Key Intermediate in Oligosaccharide Synthesis: Acts as a protected glycosyl donor or acceptor for the controlled assembly of complex carbohydrate structures.
• Pharmaceutical Research: Used in the development and synthesis of glycosylated drugs, prodrugs, and diagnostic agents.
• Glycobiology Studies: Serves as a standard or starting material for investigating enzyme mechanisms, such as those of glycosyltransferases and glycosidases.
• Fine Chemical Production: Employed in the manufacture of specialized surfactants, chiral auxiliaries, and other value-added chemical products derived from sugars.
• Material Science: Potential precursor for synthesizing sugar-based polymers or biodegradable materials with specific properties.

Quality Control

Our A-D-Maltose Octaacetate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, optical rotation measurement, and melting point determination to ensure identity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP manufacturing for pharmaceutical applications.

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). Keep away from heat, open flames, and incompatible materials. The container should be kept tightly sealed when not in use to prevent moisture absorption.
