Description

3-Ethylphenylmagnesium Bromide is a versatile organometallic reagent, specifically a Grignard reagent, widely used in organic synthesis for the formation of carbon-carbon bonds. Its primary value lies in its ability to act as a nucleophile, introducing the 3-ethylphenyl moiety into target molecules with high efficiency. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries, where it serves as a key building block for creating complex aromatic intermediates and active ingredients.

Application

• As a key nucleophilic reagent in pharmaceutical intermediate synthesis, particularly for constructing complex aryl structures.
• For the alkylation and arylation reactions in the production of fine chemicals and specialty polymers.
• In agrochemical research and development for creating novel active ingredients with specific aromatic side chains.
• As a building block in material science for synthesizing organic semiconductors and liquid crystals.
• For academic and industrial R&D in methodologies involving Grignard reactions and organometallic chemistry.
• In the synthesis of ligands and catalysts used in asymmetric synthesis and cross-coupling reactions.

Quality Control

Our 3-Ethylphenylmagnesium Bromide is manufactured and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Quality is assured through rigorous analytical testing, including titration for concentration and GC/HPLC analysis for purity and solvent composition. A comprehensive Certificate of Analysis (COA) detailing concentration, purity, and identity is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry, well-ventilated area. Due to its highly volatile, hygroscopic, and easily oxidized nature, the reagent must be handled and stored with care to prevent exposure to moisture, air, and heat sources.
