Quality Control

Our production of this advanced intermediate adheres to stringent ISO 9001 quality management standards. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and specification compliance. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and quality assurance for your formulation processes.

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 subdued lighting where practical.
