Quality Control

Our Vinyl Lithium is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including titration for assay determination and gas chromatography (GC) for solvent and impurity profiling. A Certificate of Analysis (COA) detailing purity, concentration, and solvent composition is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties as a strong base/organic solvent, highly volatile, and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures, typically between 2°C and 8°C for solutions. Store in a cool, dry, well-ventilated area away from incompatible materials.
