Quality Control

Our Diethylphenol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profile analysis, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, physical properties, and conformance are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, prolonged exposure to air, heat, or direct light should be avoided to maintain product integrity.
