Quality Control

Our Naphthoquinone Diazide Ester is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive electronic applications. Each lot is analyzed to confirm identity, purity, and performance characteristics. Certificates of Analysis (COA) detailing specific test results are provided with every shipment to support your quality assurance protocols.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, handling should be conducted under appropriate light conditions (e.g., yellow light) to prevent premature decomposition.
