Quality Control

Our production of Phosphoric Acid Diethyl(1-Methylenepropyl) Ester adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation by IR and NMR spectroscopy, and impurity profiling to ensure consistency and purity for your synthetic processes. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from strong oxidizing agents and bases.
