Quality Control

Our production of 1,5-((3,3'-Dimethylphosphate)Diphenoxy)-3-Oxapentane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your technical requirements.

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 degradation from atmospheric moisture. Keep away from incompatible materials.
