1-(2,4-Dimethylphenyl)ethanone(CAS: 89-74-7)

1-(2,4-Dimethylphenyl)ethanone (CAS: 89-74-7) is a colorless liquid with a molecular weight of approximately 154.21 g/mol. It has a low solubility in water (less than 1 g/L) but is soluble in organic solvents like ethanol and acetone. The compound is moderately reactive, particularly towards basic and reducing conditions. It crystallizes in the form of white crystals at low temperatures.

1-(2,4-Dimethylphenyl)ethanone can be synthesized through the acylation of 2,4-dimethylbenzaldehyde with acetic anhydride. This process is carried out in the presence of a suitable catalyst, such as p-toluenesulfonic acid, to promote the formation of the target compound with high yield and good selectivity.

1-(2,4-Dimethylphenyl)ethanone (CAS: 89-74-7) is primarily used in pharmaceuticals for the synthesis of certain drugs. It is also utilized in the production of polymers, specifically in the development of certain types of plastics and resins. Additionally, it finds applications in the manufacturing of sensors and semiconductors due to its chemical stability and reactivity.

When handling 1-(2,4-Dimethylphenyl)ethanone (CAS: 89-74-7), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize exposure to the vapor. Spills should be cleaned up carefully using appropriate absorbents. Always refer to the safety data sheet (SDS) for detailed emergency response procedures and storage requirements.
