Description

Dmpu-Hf Reagent CAS NO 287966-55-6 is a specialized organometallic reagent featuring a hafnium center coordinated by a dimethylpropyleneurea (DMPU) ligand. This compound is valued for its role as a highly effective catalyst and precursor in advanced synthetic chemistry, particularly for reactions requiring a strong Lewis acid in a non-coordinating, polar aprotic environment. It is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise control over polymerization and cross-coupling reactions.

Application

• As a catalyst for olefin polymerization and co-polymerization reactions.
• As a key precursor in the synthesis of other hafnium-based catalytic complexes.
• In advanced organic synthesis, facilitating C-C and C-heteroatom bond-forming reactions.
• For material science research, particularly in the development of novel inorganic-organic hybrid materials.
• In fine chemical manufacturing where high selectivity and activity are required.
• As a Lewis acid catalyst in reactions sensitive to moisture or requiring specific ligand environments.

Quality Control

Our Dmpu-Hf Reagent is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous quality testing, which may include analysis of hafnium content, ligand purity, and screening for trace metals and moisture. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its properties as a fluoride/strong alkali complex and high volatility, it must be handled under an inert atmosphere (e.g., nitrogen or argon) and kept away from moisture and incompatible materials.
