Description

4-Ethoxyphenylmagnesium Bromide is a highly reactive organometallic reagent, specifically a Grignard reagent, essential for forming new carbon-carbon bonds in complex organic synthesis. Its core value proposition lies in enabling the efficient and selective introduction of the 4-ethoxyphenyl moiety into target molecules, a key step in constructing advanced chemical intermediates. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for the production of active ingredients and functional molecules.

Application

• As a key building block in the synthesis of pharmaceutical intermediates, particularly for compounds with aryl ether functionalities.
• For the preparation of liquid crystal materials and organic electronic compounds used in display technologies.
• In agrochemical research for constructing complex molecules with potential herbicidal or insecticidal activity.
• As a reagent in coupling reactions (e.g., Kumada coupling) to create biaryl structures prevalent in many functional materials.
• For the functionalization of polymers and other macromolecules to impart specific properties.
• In academic and industrial R&D laboratories for methodological development and exploratory synthesis.

Quality Control

Our 4-Ethoxyphenylmagnesium Bromide is produced under stringent quality control protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot undergoes rigorous analysis to confirm identity, purity, and concentration, typically supplied as a solution in tetrahydrofuran or diethyl ether. Certificates of Analysis (COA) detailing exact concentration, residual base content, and other critical parameters are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as a highly volatile and easily oxidized Grignard reagent, it must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures, typically between 2°C and 8°C for extended stability. The solution is moisture-sensitive and must be handled using standard techniques for air-sensitive materials to prevent decomposition.
