Quality Control

Our 1,8-Epidithionaphthalene is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques, including HPLC and NMR, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and impurity profiles is provided with every shipment to support your research and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C to minimize oxidation and degradation. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
