Quality Control

Our Sodium Hypophosphite Monohydrate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, heavy metal content, and other critical parameters. Certificates of Analysis (COA) are provided to guarantee traceability and compliance with industry standards, supporting applications from industrial to pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation. Store separately from strong oxidizers.
