CH2CHOCOCH3n

CH2CHOCOCH3n, also known as 2-propenal or acrolein, is a colorless, flammable liquid with a pungent, irritating odor. It is a simple aldehyde with the chemical formula CH2=CHCHO. Acrolein is highly reactive and is used as a building block in the synthesis of various chemicals, including polymers and pharmaceuticals. It is also a byproduct of lipid peroxidation and is involved in the formation of advanced glycation end products (AGEs), which are associated with aging and various diseases.

Acrolein is toxic and can cause irritation to the eyes, skin, and respiratory tract. Inhalation of acrolein can lead to coughing, wheezing, and shortness of breath. Prolonged exposure can result in more severe symptoms, including pulmonary edema and respiratory failure. Acrolein is also a known carcinogen, and exposure to high concentrations can increase the risk of cancer.

Acrolein is produced naturally by various organisms, including plants and microorganisms. It is also a byproduct of incomplete combustion of organic materials, such as wood and coal. Industrial sources of acrolein include the production of acrylic acid and the manufacture of certain plastics and resins. Due to its toxicity and potential health risks, acrolein is regulated by various environmental and occupational safety standards.
