Quality Control

Our Gd(Tmhd)3 is produced under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous quality testing, which may include analysis for metal content, ligand purity, and identification of trace impurities. A Certificate of Analysis (COA) detailing specific results is provided with every shipment. We adhere to stringent internal quality standards to meet the demands of advanced materials manufacturing and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere such as argon or nitrogen when not in use to prevent degradation.
