acetalaldehyde
ethanal
Acetaldehyde is a colorless liquid with a pungent odor that is released during the oxidation of ethanol. It is a highly reactive compound and is used as a starting material in the synthesis of many chemicals, including acetic acid, ethyl acetate, and pyridines.
Acetaldehyde is primarily used in the production of plastics, synthetic rubber, and other chemicals. It is also used in the manufacture of perfumes, flavors, and fragrances due to its characteristic odor.
However, acetaldehyde is also a toxic and potentially carcinogenic compound. It is classified as a Group 1 carcinogen, which means it has the potential to cause cancer in humans. Acetaldehyde exposure can occur through inhalation, ingestion, or dermal contact.
Due to its potential danger, several regulatory bodies have established limits on the amount of acetaldehyde allowed in consumer products. For example, the US Food and Drug Administration (FDA) limits the amount of acetaldehyde in alcoholic beverages to 80mg/L. Additionally, the Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) of 200 parts per million (ppm) for acetaldehyde in the workplace.
