| Description | Formaldehyde is a colorless, strong-smelling gas with the chemical formula CH2O. It is a vital industrial chemical used in the production of numerous consumer goods, including building materials, household products, and textiles. Formaldehyde is also a significant preservative, commonly used to preserve biological specimens, such as animal tissues and cells, for scientific research. Despite its many uses, formaldehyde can be harmful to human health, causing irritation to the eyes, nose, and throat and potentially leading to long-term health effects. As a result, regulatory agencies have set limits on formaldehyde emissions and exposure levels in various settings. | CAS Common Chemistry |
