Quality Control

Our Lithium Isobutyrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity, consistent reactivity, and batch-to-batch reliability. Specifications are designed to meet the stringent requirements of research and industrial applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
