Quality Control

Our Tetraethylammonium Acetate Tetrahydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets the specified 99% purity grade. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

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 nature, the container must be kept tightly sealed after use to minimize exposure to atmospheric moisture, which can affect product quality and weight.
