Description

Maltododecaose is a defined oligosaccharide derived from starch hydrolysis, consisting of twelve glucose units linked by α-1,4 glycosidic bonds. This high-purity, well-characterized carbohydrate standard is essential for research, calibration, and quality control in analytical and life science laboratories. It serves as a critical reference material for scientists and quality assurance professionals in the pharmaceutical, food science, and biotechnology industries who require precise molecular standards.

Application

• Chromatographic Reference Standard: Primary use as a high-purity calibration standard for HPLC, GPC, and HPAEC-PAD analysis of starch hydrolysates and complex carbohydrates.
• Enzyme Substrate & Kinetics Studies: Used in biochemical research to study the activity, specificity, and inhibition of amylases, glucosidases, and other carbohydrate-active enzymes.
• Food Science Research: Serves as a model compound for investigating starch digestion, glycemic response, and the functional properties of maltooligosaccharides in product development.
• Pharmaceutical Excipient Research: Investigated for its potential as a carrier, stabilizer, or modifier in drug delivery systems due to its defined structure and biocompatibility.
• Biotechnology & Fermentation: Acts as a defined carbon source in microbial culture media for metabolic studies and the production of enzymes or specialty chemicals.
• Quality Control & Method Validation: Essential for verifying the accuracy and precision of analytical methods in QC labs for sweetener, syrup, and starch processing industries.

Quality Control

Our Maltododecaose is produced and tested to meet the exacting standards required for analytical reference materials. Each batch is characterized using advanced techniques including HPLC, mass spectrometry, and NMR to confirm identity, purity, and oligosaccharide profile. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and chromatographic data is provided with every shipment to ensure traceability and support your regulatory and research requirements.

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 purity, the container must be kept tightly sealed in a dry environment and allowed to equilibrate to room temperature before opening to prevent moisture condensation.
