Data are reported on the structural characterization of flurithromycin ethylsuccinate (FE, CAS 82730-23-2), a novel macrolide antibiotic UV, IR, NMR and MS spectra confirmed the structure, in particular the presence of ketonic-hemiketalic equilibrium, already described for flurithromycin A, is supported by NMR and HPLC studies. Moreover physico-chemical properties and stability were studied,- the product exhibits a good stability at solid state, whereas degradation products are present both in acidic and basic solution. Microbiological activity and principal pharmaceutical features were carried out.
