Quality Control

Our Tris(Hydroxypropyl)Phosphine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this product should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong oxidizers and acids.
