Novel Schiff bases have been prepared from (6R,7R)-3-[( acetyloxy)methyl]-7-[[( Z)-2-(2aminothiazol-4-yl)-2-(methoxyimino)acetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene-2carboxylate sodium and 2,4-dihydroxy benzaldehyde ,3-methoxy-4-hydroxy benzaldehyde and3,4dimethoxy benzaldehyde.The 6m homogeneity of the compounds was chered by TLC.

The structures of these Schiff bases have been characterized using IR,UV-Vis Spectroscopy, Elemental analysis(CHNS) ,melting points uncorrected ,These Schiff Power Resistance bases have been studies as Corrosion inhibitors for brass in acide media (0.5 N HCl) and antibacterial of the Schiff bases have also been tested against both Grampositive and Gram.
