Quality Control

Our (3-Ethoxycarbonyl-2-Oxopropyl)Triphenylphosphonium Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and titration methods, to ensure high chemical purity and consistent performance as a Wittig reagent. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production standards.

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). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent decomposition. Keep away from strong oxidizing agents.
