3-Bromo-5-methylaniline(CAS: 74586-53-1)

3-Bromo-5-methylaniline is a white crystalline solid with a molecular weight of 171.02 g/mol. It has a slightly soluble nature in water and is more soluble in organic solvents like ethanol and acetone. This compound is reactive towards nucleophiles and electrophiles. It is stable under normal conditions but requires storage in a cool, dry place away from strong oxidizing agents.

3-Bromo-5-methylaniline is commonly synthesized via the reaction of 5-methylaniline with bromine in the presence of a Lewis acid catalyst, such as aluminum bromide. The reaction is carried out under reflux conditions, and the yield can reach up to 90% with proper purification steps.

3-Bromo-5-methylaniline finds applications in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients (APIs) and as a precursor for dyes. It is also used in the polymer industry for the production of speciality polymers and in the sensor industry for the development of gas sensors.

When handling 3-Bromo-5-methylaniline, it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. This compound should be handled in a fume hood due to its potential volatility. Spills should be cleaned up carefully using absorbent materials, and the area should be well-ventilated. For safety and handling procedures, a Safety Data Sheet (SDS) should always be consulted.
