4953 Chloroacetaldehyde 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 (acetal), ClCH2CH(OH)2. 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. 107-20-0 C2H3ClO -16.3 °C No indication of carcinogenicity to humans (not listed by IARC). 2014-09-11T05:21:22Z 2014-12-24T20:26:59Z http://en.wikipedia.org/wiki/Chloroacetaldehyde 27871 true ClCC=O C2H3ClO InChI=1S/C2H3ClO/c3-1-2-4/h2H,1H2 InChIKey=QSKPIOLLBIHNAC-UHFFFAOYSA-N 78.498 77.987242425 Exogenous Liquid HMDB13860
