Quality Control

Our 1-Ethylpropylzinc Bromide is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm identity, purity, and concentration. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with every shipment. Our quality system supports compliance with cGMP standards for advanced intermediate production.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C or as specified on the label. Due to its hygroscopic and pyrophoric nature, the reagent must be handled in a moisture-free, oxygen-free environment using appropriate Schlenk line or glovebox techniques.
