Description

Sodium Cyclopentadienide is a versatile organometallic reagent and a powerful nucleophile, essential for synthesizing a wide range of metallocene complexes. Its primary value lies in its ability to transfer the cyclopentadienyl anion, a fundamental ligand in organometallic chemistry and materials science. This compound is critically needed by R&D laboratories and industrial manufacturers in the pharmaceutical, polymer, and specialty chemical sectors for catalyst development and advanced material synthesis.

Application

• Key precursor for synthesizing metallocene catalysts, such as ferrocene, zirconocene dichloride, and titanocene dichloride.
• Essential reagent in the production of Ziegler-Natta type olefin polymerization catalysts.
• Used in organic synthesis as a strong base and nucleophile for C-C bond formation.
• Intermediate in the manufacture of specialty chemicals and fine chemicals.
• Research and development of new organometallic compounds and catalysts.
• Potential use in the synthesis of electronic materials and precursors for chemical vapor deposition (CVD).

Quality Control

Our Sodium Cyclopentadienide is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We adhere to relevant industry standards for organometallic reagents. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee product integrity for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Due to its hygroscopic and pyrophoric nature, the container must be kept tightly sealed and handled with appropriate precautions to exclude moisture and air. Recommended storage temperature is 2-8°C for long-term stability.
