Quality Control

Our 2-Butyne-1,4-Diylbis(Diphenylphosphine Oxide) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
