Quality Control

Our Pr(Tmhd)3 is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and impurity profiling, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to prevent degradation.
