Quality Control

Our Galacturonic Acid is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect stability and handling properties.
