Bis(cyclopentadienyl)hafnium dichloride has a clear Cp₂HfCl₂ structure, making it useful as a benchmark organohafnium compound for catalyst screening, ligand modification and metallocene chemistry studies.
The two chloride ligands provide reactive sites for preparing alkyl, hydride, phosphide, substituted cyclopentadienyl or other hafnium organometallic derivatives used in advanced catalyst and materials research.
Hafnocene dichloride is a relatively high-melting solid, which can be useful for handling and purification, but users should still verify thermal behavior before heated processing.
For customers working on hafnium-based materials, HfCp₂Cl₂ offers a non-oxide, organometallic hafnium source with clear assay, chloride content and impurity specifications.
Bis(cyclopentadienyl)hafnium dichloride is used as a hafnium metallocene precursor in olefin polymerization studies, typically after activation with MAO, modified MAO, borate systems or other activators.
HfCp₂Cl₂ helps researchers compare hafnium, zirconium and titanium metallocene systems, especially when studying activity, molecular weight control, comonomer response and catalyst lifetime.
The chloride ligands in hafnocene dichloride can be replaced or transformed, making it a useful starting material for preparing modified hafnium metallocenes and post-metallocene catalyst candidates.
Use in a dry glovebox, Schlenk line or well-ventilated fume hood to reduce moisture and dust exposure.
Keep the container tightly closed and protect the product from humid air, water and accidental hydrolysis.
Wear protective gloves, lab coat, safety goggles and face protection when handling HfCp₂Cl₂.
Avoid breathing dust, fumes or vapors; use appropriate respiratory protection if ventilation is insufficient.
Thermal decomposition may release irritating gases or hydrogen chloride, so avoid uncontrolled heating.
Do not eat, drink or smoke when handling the material in the laboratory or production area.
1. What is Bis(cyclopentadienyl)hafnium dichloride?
Bis(cyclopentadienyl)hafnium dichloride is an organohafnium metallocene compound with the formula HfCp₂Cl₂. It is also called hafnocene dichloride or Cp₂HfCl₂.
2. Is HfCp₂Cl₂ moisture sensitive?
Yes. HfCp₂Cl₂ is moisture-sensitive; it should be stored in a sealed container under an inert gas atmosphere and protected from contact with water and moist air.
3. What is Bis(cyclopentadienyl)hafnium dichloride used for?
It is mainly used in organohafnium synthesis, Group 4 metallocene chemistry and catalyst research. It can also serve as a starting material for modified hafnium metallocene derivatives.
