Quality Control

Our Octyl(Tributyl)Phosphonium Chloride is produced under a rigorous quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, chloride content, and moisture is available upon request to support your quality assurance protocols.

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.
