Synthesis of some novel azo dyes and their dyeing, redox and antifungal properties

Azo dyes are widely used colorants in consumer products such as leather, textiles, agriculture, cosmetics and in laboratories as indicators. This paper describes the synthesis of some novel azo dyes starting from 3-nitro salicylic acid. The synthesized dyes were investigated for their redox potentials, evaluated for their dying ability on cotton fabrics, resistivity against the fungi growth on jowar seeds. The structure of the products was confirmed by electronic absorption, IR, 1H NMR, 13C NMR spectral studies and elemental analysis
