Quality Control

Our Potassium Nitrite is produced under strict quality management systems. We offer various grades, including Technical and Reagent grades, with specifications tailored to meet the demands of diverse industrial applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles to ensure compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, reducing agents, and combustible substances. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is 15-25°C.
