Quality Control

Our Esp CAS NO 2674-91-1 is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets stringent purity and consistency standards. A Certificate of Analysis (COA) detailing specific test results, including assay and impurity profiles, is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
