Quality Control

Every batch of In1861 is synthesized and purified under stringent, inert conditions to ensure exceptional quality and batch-to-batch consistency for sensitive cross-coupling reactions. Our products undergo rigorous quality testing, including NMR (1H, 13C), HPLC, and elemental analysis (tin content), to verify identity, purity, and the absence of catalyst poisons. Certificates of Analysis (COA) with full analytical data are provided to support your R&D and scale-up processes.

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). The material is moisture-sensitive and should be handled in a dry, inert environment to prevent decomposition. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
