SYNTHESIS OF 4-HYDROXY-2-PHENYL 6/7 SUBSTITUTED QUINOLINES AND ASSESMENT OF THEIR ANTIBACTERIAL ACTIVITY.

Industrial application of disperse dyes is based on numerous chromophore systems. Approximately 60 % of the available disperse dyes are azo based, and 25 % are anthraquinone based. Remainders of the dyes are quinaphthalene, methine, napthalimide, naphthaquinone and nitro based. The development in azo dyestuff chemistry is mainly to make in-roads into the traditional anthraquinone area. Development in azo disperse dyes over five decades have made it possible to produce a full range of colours with improved dyeing performance with better fastness properties, and also having therapeutic values. Synthesis and application of azo dyes derived from quinoline system have also been reported earlier. So this study is carried out to encourage the synthesis of some new azo disperse dyes like 4-hydroxy-2-phenyl 6/7 substituted quinolines along with their antibacterial activity.
