Quality Control

Our 4-Pentenylzinc Bromide is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm identity, purity, and concentration, typically supplied as a solution in tetrahydrofuran or diethyl ether. A Certificate of Analysis (COA) detailing specific assay results (often by titration or GC) is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere), hygroscopic (moisture-sensitive), and highly volatile, this reagent must be stored under a dry, inert atmosphere (argon or nitrogen) at recommended temperatures of 2°C to 8°C. Use appropriate ventilation and handle only in a certified fume hood.
