N,N,3-Trimethylaniline(CAS: 121-72-2)

N,N,3-Trimethylaniline is a colorless or white crystalline solid with a molecular weight of 135.17 g/mol. It is sparingly soluble in water but highly soluble in organic solvents like ethanol and acetone. Chemically, it is basic due to its amine group and can undergo reactions such as alkylation and condensation.

N,N,3-Trimethylaniline is typically synthesized by the alkylation of aniline with methanol in the presence of an acid catalyst like hydrochloric acid. The reaction is carried out at temperatures around 100°C, yielding a product with high selectivity and a good yield of about 90%.

N,N,3-Trimethylaniline is used in various industries, including pharmaceuticals for the production of certain drugs, polymers for plastic additives, sensors for gas detection, and semiconductors for manufacturing electronic components. It serves as a precursor in these applications due to its amine functionality.

When handling N,N,3-Trimethylaniline, proper personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat should be worn. Work must be conducted in a well-ventilated environment or fume hood. Spills should be cleaned up carefully using appropriate absorbents, and the material safety data sheet (MSDS) must be consulted for detailed emergency procedures.
