Quality Control

Every batch of Ethyldithiophosphonic Acid o-Methyl S-Phenyl Ester is produced and tested under a strict quality management system. We ensure high chemical purity and consistency suitable for research and industrial synthesis. Comprehensive analytical testing, including HPLC, GC, and NMR, is performed. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
