Quality Control

Our 4,6-o-3-Ketobutylidene Maltopentaose is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay by HPLC, identification by IR and NMR spectroscopy, and tests for residual solvents and moisture. Our quality system is designed to support research and development applications where reliable and reproducible material is critical.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
