Quality Control

Our Diethyl 4,4'-[Oxybis(4,1-Phenyleneimino)]Bis(4-Oxobutanoate) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment.

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 after opening to prevent degradation from atmospheric moisture.
