Quality Control

Our Electrochemical Grade Tetraethylammonium Hydrogen Phthalate is produced under stringent conditions to ensure the high purity and low trace metal content required for sensitive electrochemical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and residual solvent levels. We adhere to rigorous internal quality standards to guarantee batch-to-batch consistency and performance reliability for your research and development needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect electrochemical performance.
