C2H4Cl2O

C2H4Cl2O is the chemical formula for several isomeric compounds, meaning molecules with the same atomic composition but different structural arrangements. The most common isomers with this formula are chloroacetaldehyde and 1,1-dichloroethanol, and 2,2-dichloroethanol.

Chloroacetaldehyde (also known as 2-chloroacetaldehyde) is an organochlorine compound and an aldehyde. It is a colorless liquid with a pungent odor. Chloroacetaldehyde is soluble in water and organic solvents. It is a reactive compound and can undergo various chemical reactions, including polymerization and oxidation. Industrially, it is used as an intermediate in the synthesis of other chemicals, such as pharmaceuticals and pesticides. It can also be found as a metabolite of other chlorinated compounds. Exposure to chloroacetaldehyde can be irritating to the skin, eyes, and respiratory tract.

1,1-dichloroethanol and 2,2-dichloroethanol are both chlorinated alcohols. These isomers are less commonly encountered than chloroacetaldehyde. Their properties and uses vary depending on the specific isomer and its stability. Dichloroethanols can be formed as byproducts in certain industrial processes or as intermediates in chemical synthesis. Their environmental and health impacts are also dependent on the specific compound.
