Description

Phenyl Sodium 25% Solution in Heptane is a highly reactive organometallic reagent, specifically a sodium salt of benzene. This product is valued for its powerful nucleophilic and basic properties, making it an essential intermediate in advanced organic synthesis. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for demanding reactions such as deprotonation and metal-halogen exchange.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the formation of carbon-carbon bonds and the preparation of complex aromatic compounds in API development.
• Polymerization Catalyst/Initiator: Used in anionic polymerization processes to produce specialized polymers and elastomers with controlled molecular weights.
• Fine Chemical Manufacturing: Employed in the synthesis of dyes, pigments, and other high-value aromatic specialty chemicals.
• Agrochemical Production: Serves as a building block in the synthesis of certain herbicides and pesticides that require phenyl group incorporation.
• Research & Development: A critical tool in academic and industrial labs for exploring new synthetic methodologies and organometallic chemistry.
• Metal-Halogen Exchange Reactions: Facilitates the preparation of other organometallic reagents by exchanging sodium for other metals in organic halides.

Quality Control

Our Phenyl Sodium 25% Solution in Heptane is manufactured under stringent controls to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm concentration, purity, and the absence of detrimental impurities. A comprehensive Certificate of Analysis (COA) detailing assay (by titration), solvent content, and stability indicators is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and pyrophoric nature, the solution must be handled exclusively under inert conditions. Recommended storage temperature is 2-8°C (refrigerated) for extended stability.
