Quality Control

Our production of Diphenyl[3-(Triethoxysilyl)Propyl]Phosphine adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including NMR, GC, and HPLC, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to minimize degradation. Due to its hygroscopic and oxidatively sensitive nature, containers should be flushed with inert gas after each opening.
