Description

4-Bromophenylzinc Iodide is a versatile organozinc reagent, specifically an arylzinc halide, widely used in cross-coupling reactions for the efficient introduction of the 4-bromophenyl moiety. Its core value proposition lies in its high reactivity and selectivity in Negishi and related coupling protocols, enabling the streamlined synthesis of complex biaryl and functionalized aromatic structures. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable building blocks for constructing carbon-carbon bonds.

Application

• Key intermediate in Negishi cross-coupling reactions for the synthesis of biaryl compounds.
• Building block for pharmaceutical active ingredients (APIs) and agrochemicals requiring brominated aromatic cores.
• Precursor in the synthesis of liquid crystal materials and organic electronic compounds.
• Reagent for polymer modification and the creation of functionalized monomers.
• Used in academic and industrial R&D for method development and library synthesis.
• Facilitates the preparation of ligands for catalysis and metal-organic frameworks (MOFs).

Quality Control

Our 4-Bromophenylzinc Iodide is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes rigorous analytical testing, including titration for active zinc content and spectroscopic analysis for identity and purity verification. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle and store the product under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal purity and reactivity. Recommended storage temperature is 2-8°C for long-term stability.
