Maleic acid hydrazide

The unsubstituted phthalic acid hydrazide and several nonaromatic cyclic hydrazides such as maleic acid hydrazide or succinic acid hydrazide are either nonchemiluminescent or show extremely weak CL. However, the 6-amino isomer of luminol, which is called isoluminol, is chemiluminescent to about the same extent as is luminol. Isoluminol has been used in many chemiluminescent studies, and because the amino group is less sterically hindered than that of luminol, it is probably derivatized for chemiluminescent labeling far more often than is luminol (Fig. 3). [Pg.109]

The structure of maleic acid hydrazide, l,2-dihydropyridazine-3,6-dione, has been investigated using H NMR, IR, and Raman spectra. In the average, 23% of the four protons of maleic hydrazide are in rapid exchange and 77% of them are position-fixed. [Pg.66]
