Quality Control

Our Menadione Nicotinamide Bisulfite is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) are provided with every shipment, detailing results for key parameters such as assay, related substances, and residual solvents. We can support compliance with relevant standards for feed and nutritional applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
