Quality Control

Our 1,3-Oxaphosphol-5(2H)-One, 3,3-Dihydro-2-(Phosphinomethylene)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistent performance for research and development applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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.
