Quality Control

Our Lithium Di-n-Butyl-S-Butyl Magnesiate 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 solution concentration (typically supplied in hydrocarbon solvents). We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and moisture content. Our quality system is designed to meet the exacting standards of research and process chemistry applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area. Due to its hygroscopic and pyrophoric nature, the reagent must be handled exclusively under inert conditions using appropriate techniques. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, open flames, and oxidizing agents.
