Quality Control

Our (4-Methylene-5-Hexenyl)Triphenyl-Phosphonium Iodide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the exacting standards required for synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment to support your quality and regulatory compliance.

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.
