Quality Control

Our 5-Ethoxy-5-Oxopentylzinc Bromide is produced under stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes rigorous analytical testing, including titration for active zinc content and spectroscopic identification. Certificates of Analysis (COA) detailing purity, concentration (typically supplied as a solution in THF or diethyl ether), and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is easily oxidized (store under inert atmosphere) and highly volatile. It must be handled and stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature for solutions is 2-8°C. Keep away from strong acids/organic solvents and moisture.
