Quality Control

Our Sodium Hydrogen D-Glucarate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent specifications suitable for food, pharmaceutical, and industrial applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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 lead to caking or degradation.
