Quality Control

Our Dipotassium Fumarate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and safety. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements, including those for food-grade (FCC) and pharmaceutical applications.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
