Quality Control

Every batch of Lanthanum Tris[Bis(Trimethylsilyl)Amide] is manufactured and handled under strict inert atmosphere conditions to ensure purity and consistency. Our products undergo rigorous quality testing, including spectroscopic analysis and elemental assay, to ensure compliance with exacting research and high-tech industry standards. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and trace metal content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place. Due to its highly moisture-sensitive and easily oxidized nature, this material must be handled exclusively in a glovebox or using rigorous Schlenk line techniques. Recommended long-term storage temperature: 2°C to 8°C. Allow the sealed container to reach room temperature before opening to prevent condensation.
