Quality Control

Our 4,5-Diphenyl-2-(n-Ethyl-n-(2-Hydroxyethyl)Amino)Oxazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, spectroscopic identification, and loss on drying, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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.
