Quality Control

Our Dilithium S-Ethyl Thiophosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) that include assay, impurity profile, and physical characterization data, supporting compliance with cGMP and ISO 9001 standards for industrial and research use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the material should be handled under an inert atmosphere (e.g., nitrogen or argon) and the container kept sealed to minimize exposure to moisture and air.
