The titled Schiff base, 6-amino-2-[(4-(dimethylamino)benzylidene)amino]hexanoic acid was synthesized by condensing N,N-dimethyl aminobenzaldehyde and Lysine together using ethanol as a solvent.
Schiff base compounds have been extensively studied because of their biological and structural importance [21-23] and especially their specific and selective reactions with metal ions.

Novel homologous polyphosphoesters, namely, poly[oxyethylene (aminophosphonate-co-Hphosphonate)]s P-12 and P-13 (Scheme 1), which contain anthracene- and furan-derived aminophosphonate units, have been synthesized through an addition of poly(oxyethylene H-phosphonate) 1 to the Schiff base 9-anthrylidenefurfurylamine S-2.
The phenolic -OH stretching frequency at 1267 [cm.sup.-1] found in the spectrum of the Schiff base was absent in the spectra of metal complexes and might be due to the coordination of the phenol oxygen atom involved in complexation as C-O-M at ~1224[cm.sup.-1] [46].

Obtained results indicated that salicylaldehyde-hydrazine hydrate Schiff base (compound la) displayed an activity for inhibiting the growth of S.
Hydrazone Schiff base plays an important role in inorganic chemistry, as it can easily form stable complexes with most transition metal ions due to its ability to form keto-enol tautomerism (Figure 1) [1-4].
