2-Methylcyclopentanone(CAS: 1120-72-5)

2-Methylcyclopentanone (CAS: 1120-72-5) is a colorless, flammable liquid with a molecular weight of 102.17 g/mol. It has a density of 0.815 g/cm³ and is slightly soluble in water but soluble in ethanol and other organic solvents. It is reactive towards strong oxidizing agents and can undergo dehydration and isomerization under certain conditions.

2-Methylcyclopentanone can be synthesized via the oxidation of 2-methylcyclopentanol using potassium permanganate or potassium dichromate. Another route involves the reaction of cyclopentanone with methyl iodide in the presence of a base such as sodium hydride.

2-Methylcyclopentanone is used in the pharmaceutical industry for the synthesis of various organic compounds, in the polymer industry for the production of plastics and resins, and in the sensor industry for gas detection applications. It is also employed in the semiconductor industry for photoresist materials.

When handling 2-Methylcyclopentanone (CAS: 1120-72-5), wear appropriate personal protective equipment (PPE) including gloves, lab coat, and safety goggles. Store it in a cool, well-ventilated area away from heat and ignition sources. In case of a spill, use appropriate absorbents and ensure proper disposal. Always consult the Safety Data Sheet (SDS) for detailed handling instructions.
