Quality Control

Our 2,3-Diamino-5-Chloropyrazine is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for pharmaceutical and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

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