Quality Control

Our 2,6-Dichlorobenzyl 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. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 and maintain reagent efficacy.
