C2H3Cl2O

C2H3Cl2O is the molecular formula for several chemical compounds, indicating the presence of two carbon atoms, three hydrogen atoms, two chlorine atoms, and one oxygen atom in each molecule. The specific arrangement of these atoms determines the compound's identity and properties. Common isomers with this formula include dichloroacetaldehyde and 1,1-dichloroethanol.

Dichloroacetaldehyde (also known as chloral or trichloroacetaldehyde hydrate when hydrated) is a chlorinated aldehyde. It is a colorless liquid with a pungent odor. Dichloroacetaldehyde is an intermediate in the synthesis of various organic chemicals and has been used historically as a sedative and hypnotic, although its use for this purpose has largely been discontinued due to safety concerns and the availability of better alternatives.

1,1-Dichloroethanol is a chlorinated alcohol. It is a colorless liquid and is less commonly encountered than dichloroacetaldehyde. Its properties and uses are distinct from those of the aldehyde. The chemical behavior of compounds with the formula C2H3Cl2O is influenced by the presence of both chlorine and oxygen atoms, leading to potential reactivity in various chemical processes.
