Quality Control

Our production of this high-purity photochemical adheres to strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized by multiple analytical techniques including HPLC, NMR, and FT-IR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and performance in standard application tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled temperature of 15-25°C (59-77°F) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and decomposition. Keep away from heat, sparks, and open flame. The container must be kept tightly sealed in a dry environment to minimize exposure to atmospheric moisture.
