CAS No. 1066-54-2 is an organic compound known as cyclohexanone, which is a colorless liquid with a faint sweet odor. It is a cycloalkanone, with a six-membered ring of carbon atoms. This compound is used as a solvent in chemical and pharmaceutical industries, as well as in the production of dyes, resins, and other chemicals. It is also used in the production of perfumes and fragrances.

Cyclohexanone is used as a starting material for the production of caprolactam, which is an important intermediate used in the manufacture of nylon 6. It is also used as a starting material in the production of adipic acid, which is used in the production of nylon 6,6. In addition, cyclohexanone is used as a raw material for the production of cyclohexanol, which is used in the production of various pharmaceuticals, fragrances, and other chemicals.

Cyclohexanone is a volatile organic compound that is classified as a hazardous air pollutant. It has a low acute toxicity, but repeated exposure can cause skin and eye irritation. The Occupational Safety and Health Administration (OSHA) has established exposure limits for cyclohexanone of 0.5 ppm as an 8-hour time-weighted average.

Cyclohexanone is readily biodegradable and has a low potential for bioaccumulation. It is not persistent in the environment, and its toxicity to aquatic organisms is low. It is not classified as a carcinogen.

Cyclohexanone is a flammable liquid, and should be stored in a cool, dry, and well-ventilated area away from sources of ignition and heat. It should be handled with caution and appropriate safety measures should be taken when handling and storing this compound.
