Quality Control

Every batch of In1654 is synthesized and purified under stringent conditions to ensure high chemical purity and optimal performance in sensitive coupling reactions. Our quality assurance includes comprehensive analytical characterization using techniques such as NMR, HPLC, and elemental analysis. A Certificate of Analysis (COA) detailing batch-specific purity, identity, and residual solvent levels is provided with each shipment to support your R&D and quality protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store the product in a freezer at -20°C to -10°C under an inert atmosphere (argon or nitrogen). Allow the sealed container to reach room temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
