This study aims to focus on the possibility of developing new thiazole azo dyes with good colouristic application properties, biological and pharmacological activities.
Coupling of curcumin with different aromatic diazonium salts of 2-amino thiazole derivatives, such as 2-aminobenzothiazole, 2-amino-5-phenylthiazole, 2-amino-5-methylthiazole and 2-amino-5-nitrothiazole-produced novel azo dyes. Structures of all synthesised dyes were fully confirmed via spectroscopic and analytical methods. Those compounds were examined for their antimicrobial, anticancer and antioxidant activities. They were applied on polyester fabrics and, subsequently, their dyeing properties, light, washing, perspiration, rubbing and sublimation fastness were determined.
Prepared dyestuffs were suitable for dyeing polyester fabrics. It was found that all prepared dyes possess high colour strength, as well as good overall fastness properties. Meanwhile, the synthesised compounds exhibited good biological and pharmacology activity.
Synthesis of these four azo dyes for textile dyeing was not conveyed earlier.
Thaizolyl disperse dyes were responsible for giving better colour assessment and fastness properties on polyester fabrics.
Although, most of synthesis eco-friendly dyes are expensive, they are showing a good antimicrobial and anticancer activity.
It gave straightforward approach to synthesise novel thiazolyl azo dyes with good biological, pharmacology activities, good colour assessment, and fastness properties.
