Quality Control

Our Phosphine, Ethynyldiphenyl- is produced and handled under strict quality protocols to ensure batch-to-batch consistency and purity for research and development applications. Each lot undergoes comprehensive analytical characterization, including NMR (¹H, ³¹P) and GC or HPLC analysis. Certificates of Analysis (COA) detailing purity and identity are available upon request.

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 for long-term stability. Due to its sensitivity, allow the container to reach room temperature before opening to minimize moisture ingress.
