Description

4-(2-Bromoethoxy)Benzonitrile is a versatile organic building block featuring both a bromoalkoxy linker and a benzonitrile moiety. This bifunctional structure makes it a critical intermediate for the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists in the fine chemical and life sciences industries for constructing novel compounds and active ingredients.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring an ethoxy-linked aromatic nitrile scaffold.
• Agrochemical Synthesis: Used in the research and development of herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & OLED Material Research: Serves as a building block for creating advanced organic electronic materials and liquid crystal compounds.
• Polymer Chemistry: Employed in the modification of polymers and the synthesis of specialty monomers with specific functional groups.
• Cross-Coupling Reactions: The bromine atom is reactive in palladium-catalyzed couplings (e.g., Suzuki, Heck), while the nitrile group offers further derivatization potential.
• Chemical Biology & Proteomics: Useful for synthesizing molecular probes, affinity labels, and linker molecules for bioconjugation.

Quality Control

Our 4-(2-Bromoethoxy)Benzonitrile is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, documenting all critical parameters. Our quality systems support development and cGMP manufacturing requirements for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
