Quality Control

Every batch of our (R)-Biphenyl-(3,4-Dimethyl-1-Cyclopentadienyl)-Titanium(Iv)-(R)-1,1'-Binaphthyl-2 is manufactured and tested under strict quality management systems. We ensure compliance with rigorous internal specifications to guarantee high chiral purity and chemical integrity for catalytic applications. A comprehensive Certificate of Analysis (COA), detailing chiral purity, assay, and identity confirmation, is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store the product under an inert atmosphere (argon or nitrogen) at 2-8°C. This material is easily oxidized and light-sensitive; prolonged exposure to air, moisture, or ambient light will degrade its catalytic activity. The storage area should be cool, dry, and well-ventilated.
