Quality Control

Our Ho(Tmhd)3 is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including NMR, FT-IR, and elemental analysis (ICP-OES). A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from incompatible materials.
