1-(2,3-Dimethylphenyl)ethanone(CAS: 2142-71-4)

1-(2,3-Dimethylphenyl)ethanone (CAS: 2142-71-4) is a colorless liquid with a molecular weight of approximately 150.23 g/mol. It has a solubility of about 12.5 g/L in water and a slight reactivity towards strong bases. It is crystalline at temperatures below -10°C and has a melting point of -16°C and a boiling point of 128°C. It is slightly soluble in water and highly soluble in common organic solvents.

1-(2,3-Dimethylphenyl)ethanone (CAS: 2142-71-4) can be synthesized via the Klüwer reaction, where 2,3-dimethylbenzaldehyde is reacted with ethyl acetate in the presence of a base like sodium hydroxide. The product is isolated by recrystallization and yields up to 95% purity. This method is known for its high efficiency and selectivity.

1-(2,3-Dimethylphenyl)ethanone (CAS: 2142-71-4) is used in the pharmaceutical industry for the synthesis of certain intermediates. It also finds applications in the polymer industry as a monomer and in the production of sensors and semiconductors. Its use in these industries leverages its chemical reactivity and solubility properties.

When handling 1-(2,3-Dimethylphenyl)ethanone (CAS: 2142-71-4), it is essential to wear personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be used in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbent materials, and the area should be well ventilated. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
