Quality Control

Our 4,4'-Bis[(2-Hydroxyethyl)Methylamino]Benzophenone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent in-house specifications, which typically include identity confirmation, assay (purity), and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which could affect product quality.
