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 purity, identity, and safety. Certificates of Analysis (COA) are provided and the product can be supplied to meet various standards, including Food Chemical Codex (FCC) and pharmaceutical-grade requirements, 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). 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.
