Quality Control

Our Tetrakis(Hydroxymethyl)Phosphoniumiodide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA), detailing assay, identity, and impurity profiles, is provided with every shipment to guarantee compliance with your specifications and industry standards.

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 and stability.
