Synthesis and antibacterial studies of azodispersed dyes derived from 2-(thiazol-2-yl)phthalazine-1,4-diones Synthesis and antimicrobial of new anthraquinone derivatives incorporating pyrazole moiety

Abstract A dibenzobarrelene derivative was used as key intermediate for the synthesis of 2-(4-(methyl/phenylthiaz-ol-2-yl)-2,3,4a,5,10,10a-hexahydro-5,10-benzenobenzo[g]phthalazine-1,4-diones. These compounds were coupled with the appropriate diazonium chlorides to give the corresponding 5-(arylazo)thiazole derivatives. The synthesized dyes were applied to polyester as disperse dyes, and their antibacterial, color measurement, and fastness properties were evaluated.
