Quality Control

Our Lithium, 1,3-Dithian-2-Yl- is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Quality is verified through analytical techniques including titration and NMR to confirm reactivity and purity. A Certificate of Analysis (COA) detailing specific batch characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this material must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures of 2°C to 8°C. Handle only in a certified fume hood using appropriate techniques for air- and moisture-sensitive compounds.
