Quality Control

Our n-Nonylbutyllithium is manufactured under stringent conditions to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical techniques including titration for active lithium content and GC analysis for hydrocarbon purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and solution concentration is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this product must be stored under a dry, inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C. Handle only in a certified fume hood or under an inert gas blanket to prevent decomposition and ensure safety.
