(organic chemistry)
NCCH2COOH Hygroscopic crystals with a melting point of 66°C; decomposes at 160°C; soluble in ether, water, and alcohol; used in the synthesis of intermediates and in the commercial preparation of barbital. Also known as malonic mononitrile.

Summary: A monobasic bidentate ligand (H2L) was prepared from the reaction of cyanoacetic acid hydrazide with 1-(4-((1H-imidazol-2-yl)sulfonyl)phenyl)ethanone (ISE) in ethanol.
Firstly, the vibrational modes of the azomethine group, (-C=N-), were identified by comparing the infrared spectra of (ISE) and cyanoacetic acid hydrazide, in which (C=O) and (NH2) in cyanoacetic acid hydrazide were obscured.
In the subsequent step, the dye Co-D-Ac was prepared by a Knoevenagel condensation reaction using 9 and cyanoacetic acid 10 in acetonitrile as solvent and pyridine as catalyst, to obtain an orange solid in good yield, this solid showed a band at 2212 [cm.
