Quality Control

Our 1,3,4,2-Oxadiazaphosphole-3(2H)-Carboxylic Acid, 2,2-Dihydro-5-Methoxy-, Methyl Ester, Conjugate Monoacid (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the exacting standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and other critical parameters is provided with each shipment.

Storage

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