This paper aims to synthesise some novel diazobenzene dyestuffs clubbed with sulphonamide moiety and their application for polyester fabrics in addition to evaluating their biological activities.


New diazobenzene disperse dyes with improved chemical construction via sulphonamides were designed. This amendment of diazobenzene dyes was completed by introducing sulphonamide derivatives through Japp–kilingman reaction. All new synthesised dyes were elucidated by elemental analyses and spectral data (IR and 1 H-NMR). Biological activities of the synthesised diazobenzene sulphonamide derivatives were evaluated.


The synthesised diazobenzene dyestuffs clubbed with sulphonamides were applied on polyester fabrics. The synthesised dyes showed that good fastness properties and their biological evaluation exhibited good efficacy towards antibacterial, antioxidant and anticancer.


Sulphonamide derivatives have numerous uses, such as being used in dyestuff and providing antimicrobial, antioxidant, and anticancer properties. Sulphonamide derivatives with diazobenzene coupler components exhibited an interesting colorant for polyester and provided better biological efficacy for other non-textile applications. This work afforded new disperse dyes beside their medical applications.
