Formaldehyde

Formaldehyde is an organic compound with the formula CH2O. It is the simplest form of aldehyde, hence its systematic name methanal. The common name of the substance comes from its similarity and relation to formic acid.

A gas at room temperature, formaldehyde is colorless and has a characteristic pungent, irritating odor. It is an important precursor to many other chemical compounds, especially for polymers. In 2005, annual world production of formaldehyde was estimated to be 23 million tonnes (50 billion pounds). Commercial solutions of formaldehyde in water, commonly called formalin, were formerly used as disinfectants and for preservation of biological specimens.

In view of its widespread use, toxicity and volatility, exposure to formaldehyde is a significant consideration for human health. On 10 June 2011, the US National Toxicology Program described formaldehyde as "known to be a human carcinogen".
