Product Description of Formaldehyde CAS#50-00-0
Formaldehyde is the simplest member of the aldehyde family and is characterized by its high chemical reactivity and inherent toxicity. Under ambient conditions, it is a colorless gas with a distinctive, pungent odor. Due to its reactive nature, formaldehyde can readily undergo polymerization, producing polyformaldehyde.
Formaldehyde is highly soluble in water and also dissolves readily in alcohols and various organic solvents. In the environment, formaldehyde is released from a range of sources, including fuel combustion, industrial activities, construction and interior decoration materials, and numerous household and consumer products.
