Special Hazards of Combustion Products: Toxic oxides of nitrogen and toxic and flammable acetonitrile vapors may form in fire.
ChEBI: A monocarboxylic acid that consists of acetic acid bearing a cyano substituent.
Yellow-brown liquid with an unpleasant odor. Sinks and mixes with water.
Cyanoacetic acid was used in the synthesis of N-piperidine-cyanacetamide and N-morpholyl-cyanacetamide. It was also used in the preparation of a panchromatic dye for dye-sensitized solar cells.
Recrystallise the acid to constant melting point from *benzene/acetone (2:3), and dry it over silica gel. [Beilstein 2 H 583, 2 I 253, 2 II 530, 2 III 1626, 2 IV 1888.]
Synthesis of intermediates; manufacture of barbital.
Contact irritates eyes and may irritate skin.
White, moderately toxic solid, combustible. When heated to decomposition Cyanoacetic acid emits toxic fumes of nitrile and oxides of nitrogen. A stirred mixture with furfuryl alcohol exploded violently upon heating [MCA Case History No 858].
white to light beige adhering crystalline solid
