Quality Control

Our Benzhydrol, 4,4'-Dimethyl-, Lithium Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability for critical applications. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept sealed and handled under inert conditions to maintain purity and reactivity.
