Quality Control

Our E-(2-Ethoxy-Propenyl)-Triphenyl-Phosphonium Iodide Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity for synthetic applications. Each lot undergoes comprehensive analytical testing, including NMR, HPLC, and titration methods, to confirm identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We support compliance with REACH and other global regulatory frameworks as required.

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 nature, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
