For professionals working with chemical intermediates, a thorough understanding of a compound's properties and safe handling procedures is critical. 5-Bromo-2-fluorobenzonitrile (CAS 179897-89-3) is a valuable synthetic intermediate, and knowledge of its physical and chemical characteristics ensures efficient and safe usage in laboratories and production facilities.

Key Chemical and Physical Properties

5-Bromo-2-fluorobenzonitrile is typically described as a white powder. Its molecular formula is C7H3BrFN, with a molecular weight of approximately 200.01 g/mol. The melting point generally falls within the range of 75-77 °C or 76-80 °C, indicating it is a solid at standard room temperature. The boiling point is reported at 220.4 °C at 760 mmHg, suggesting it is a relatively stable compound under normal atmospheric pressure. Its solubility characteristics are important for reaction planning; while specific details may vary, many aromatic nitriles exhibit moderate solubility in common organic solvents.

The chemical reactivity of 5-Bromo-2-fluorobenzonitrile is largely dictated by its functional groups. The bromine atom is susceptible to nucleophilic aromatic substitution under certain conditions or can be activated for cross-coupling reactions. The fluorine atom imparts electron-withdrawing characteristics, influencing the reactivity of the aromatic ring and the nitrile group. The nitrile group can undergo hydrolysis, reduction, or addition reactions, providing numerous avenues for further chemical modification.

Safe Handling and Storage Recommendations

When you purchase and use 5-Bromo-2-fluorobenzonitrile, adhering to safety protocols is paramount. As with many fine chemicals, it is advisable to handle it in a well-ventilated area, preferably a fume hood, to avoid inhalation of dust or vapors. Personal protective equipment (PPE) such as safety goggles, chemical-resistant gloves, and laboratory coats should always be worn.

Specific storage recommendations typically include keeping the container tightly closed in a cool, dry place, away from direct sunlight and incompatible materials. Incompatible substances might include strong oxidizing agents or strong bases that could react with the nitrile or halogen groups. Ensuring proper storage helps maintain the compound's purity and prevents degradation over time.

Procurement specialists and laboratory managers should always consult the Safety Data Sheet (SDS) provided by the manufacturer or supplier for the most accurate and up-to-date information regarding handling, storage, and emergency procedures. Reliable suppliers, including those in China, will ensure these documents are readily available when you buy 5-Bromo-2-fluorobenzonitrile, supporting your commitment to laboratory safety and product integrity.
