Description

Maltopentaose Hydrate is a defined oligosaccharide consisting of five glucose units linked by α-1,4 glycosidic bonds. This high-purity carbohydrate standard is critical for analytical calibration, method development, and research in enzymology and carbohydrate chemistry. It serves as an essential reference material for scientists and quality control professionals in the pharmaceutical, food science, and biotechnology industries. Maltopentaose Hydrate CAS NO 123333-77-7 is valued for its consistency and defined structure in complex biochemical studies.

Application

• Analytical Reference Standard: Primary use as a calibration standard in High-Performance Liquid Chromatography (HPLC) and Size-Exclusion Chromatography (SEC) for the analysis of starch hydrolysates, syrups, and other oligosaccharide mixtures.
• Enzyme Substrate & Research: Serves as a specific substrate for studying the activity, kinetics, and inhibition of enzymes like α-amylase, glucoamylase, and other starch-degrading enzymes.
• Biochemical & Nutritional Research: Used in metabolic studies to investigate carbohydrate digestion, glycemic response, and as a component in defined culture media for microbiological research.
• Food Science & Development: Acts as a model compound for understanding starch functionality, sweetness profiles, and the development of specialized nutritional products.
• Pharmaceutical Excipient Research: Investigated for its potential functional properties as a carrier, stabilizer, or taste-masking agent in novel drug formulations.
• Diagnostic Reagents: Utilized in the formulation of reagents and kits for clinical diagnostics related to carbohydrate metabolism and pancreatic function.

Quality Control

Every batch of Maltopentaose Hydrate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity requirements for research and analytical applications. A detailed Certificate of Analysis (COA) specifying purity (by HPLC), water content, and identification is supplied with each shipment. Our quality commitment supports compliance with relevant research and analytical standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To maintain stability and prevent clumping or degradation, the container must be kept tightly sealed in a low-humidity environment after opening.
