3-Bromoaniline (m-Bromoaniline) is a halogenated aniline derivative widely used as a pharmaceutical intermediate in the synthesis of antimalarial drugs (e.g., chloroquine analogs) and azo dyes. This compound exhibits a melting point of 16.8°C, boiling point of 251°C at 760 mmHg, and density of 1.579 g/cm³ (20°C). It is soluble in ethanol/ether but poorly soluble in water. Storage requires protection from light at 2-8°C under inert atmosphere due to sensitivity to oxidation. Safety precautions are critical as it may form methemoglobin (GHS Category 2), requiring PPE including chemical goggles and nitrile gloves. The bromine atom at meta-position enables diverse electrophilic aromatic substitution reactions.
