Quality Control

Every batch of (1-Iodo-1-Penten-5-Yl)Triphenylphosphonium is manufactured and tested under strict quality management protocols to ensure consistency and reliability for sensitive synthetic applications. Our products undergo rigorous quality testing, including NMR and HPLC analysis, to ensure compliance with exacting R&D and process chemistry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
