Chloroacetaldehyde  Chloroacetaldehyde is an 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 hemiacetal (ClCH2CH(OH))2O. Chloroacetaldehyde is a useful intermediate in the synthesis of 2-aminothiazole including the pharmaceuticals altizide, polythiazide, brotizolam and ciclotizolam. Another use is to facilitate bark removal from tree trunks. Hydrated chloroacetaldehyde is produced by the chlorination of aqueous vinyl chloride: It can also be prepared from vinyl acetate or by careful chlorination of acetaldehyde. The related bromoacetaldehyde is prepared via bromination of vinyl acetate. It also rapidly forms an acetals in the presence of alcohols. Being bifunctional, chloroacetaldehyde is a versatile precursor to many heterocyclic compounds. It condenses with thiourea derivatives to give aminothiazoles. This reaction was important as a precursor to sulfathiazole, one of the first sulfa drugs. Water free chloroacetaldehyde is prepared from the hydrate by azeotropic distillation with chloroform, toluene or carbon tetrachloride.
