Synthesis, characterization and solvatochromic spectra of novel thiazole based azo dye

The present research article describes about the synthesis of novel thioazole based azo dye N-(4- chloro - 2- methyl phenyl) – 4 - {(Z) - [4-(4-ethyl phenyl)-1,3-thiazol-2-yl] diazenyl}-3 - hydroxy naphthalene-2-carboxamide (4), by the diazotization of 4-(4-ethyl phenyl) thiazol - 2 - amine (2) and coupling with N-(4- chloro – 2 – methyl phenyl) – 3 –hydroxyl naphthalene – 2 - carboxamide (3) under suitable optimized experimental conditions to yield a disperse azo dye suitable for dying hydrophobic fibers and fabrics. It imparts deep reddish brown colour to the fabric. The synthesized compound was characterized completely by various analytical techniques like elemental analysis, IR spectral, 1H NMR, 13C NMR and LCMS (Liquid chromatography Mass spectroscopy).
