Quality Control

Every batch of this specialty chemical is produced and tested under strict quality management protocols to ensure consistency and purity for sensitive electronic applications. Our standard grade typically meets a purity specification of ≥97.0% (HPLC), with stringent control over key impurities. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and residual solvent content is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the original container has been opened. Keep away from heat and incompatible materials.
