Quality Control

Our Methyl-Phosphinic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) are available upon request to provide full transparency on purity, identity, and other critical parameters.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
