Quality Control

Our Sodium Hypophosphite Monohydrate is manufactured under a strict quality management system. Products undergo rigorous testing to ensure they meet the high-purity standards required for industrial and specialty applications. A comprehensive Certificate of Analysis (COA) is provided with each batch, detailing key parameters such as assay, moisture content, and impurity levels. We can supply material compliant with various industry standards, including technical, food (FCC), and pharmaceutical grades, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize quality degradation. Keep away from strong oxidizing agents and heat sources.
