About this item

IUPAC name	2-chloroacetaldehyde
canonical smiles	C(C=O)Cl
inchi	InChI=1S/C2H3ClO/c3-1-2-4/h2H,1H2
inchi key	QSKPIOLLBIHNAC-UHFFFAOYSA-N
molecular formula	C2H3ClO
synonyms	CHLOROACETALDEHYDE 2-chloroacetaldehyde 107-20-0 Chloroethanal 2-Chloroethanal
Compound Description	2-chloroethanal appears as a clear colorless liquid with a pungent odor. Flash point about 190 °F. Corrosive to skin and mucous membranes. It is very toxic by inhalation. Chloroacetaldehyde is acetaldehyde substituted at C-2 by chlorine. It is functionally related to an acetaldehyde. Being bifunctional, chloroacetaldehyde is a versatile precursor to many heterocyclic compounds. It condenses with thiourea derivatives to give aminothiazoles. This reaction was once important as a precursor to sulfathiazole, one of the first sulfa drugs. Chloroacetaldehyde is the organic compound with the formula ClCH2CHO. Like some related compounds, it is highly electrophilic reagent and a potentially dangerous alkylating agent. The compound is not normally encountered in the anhydrous form, but rather as the hydrate , ClCH2CH2. Chloroacetaldehyde is a useful intermediate in the synthesis, e.g. of 2-aminothiazole or many pharmaceutical compounds. Another use is to facilitate bark removal from tree trunks.
