Quality Control

Our Etimizol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which typically include assay, identification, and impurity profile analysis. A Certificate of Analysis (COA) detailing all test results is provided with every 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). Keep away from heat sources and incompatible materials such as strong acids and oxidizing agents. The container must be kept tightly sealed due to the compound's hygroscopic nature.
