3-Methoxy-2-methylaniline(CAS: 19500-02-8)

3-Methoxy-2-methylaniline is a pale yellow to white crystalline solid with a molecular weight of approximately 158.19 g/mol. It has a moderate solubility in water (2.5 g/100 mL at 20°C) and high solubility in organic solvents like ethanol and acetone. The compound is moderately reactive, showing basic behavior due to the amine group, and it can undergo electrophilic aromatic substitution reactions.

3-Methoxy-2-methylaniline is commonly synthesized by the reaction of 2-methylaniline with methanol in the presence of an acid catalyst, such as sulfuric acid. The process involves a methylation step followed by an amine substitution to form the final product. The yield is typically around 70-80%, and the method is selective and efficient for industrial-scale production.

3-Methoxy-2-methylaniline is primarily used in the pharmaceutical industry as an intermediate in the synthesis of certain drugs. It is also utilized in the production of dyes, pigments, and as a precursor for the synthesis of other organic compounds. Additionally, it has applications in the polymer industry for the development of certain types of plastics and resins.

When handling 3-Methoxy-2-methylaniline, it is important to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work should be conducted in a fume hood due to its potential to release volatile fumes. Spills should be handled by absorbing them with a suitable material and disposing of the waste according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling and emergency procedures.
