Quality Control

Our Ethylenebis(Trioctylphosphonium) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and titration methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong oxidizing agents.
