Quality Control

Every batch of this high-purity fluorinated intermediate is produced and analyzed under strict quality management protocols. We employ advanced analytical techniques including HPLC, NMR, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, chiral purity, and impurity profiles is provided with each shipment to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment. For long-term storage, consider using desiccants or an inert atmosphere.
