Abstract: This study explores the synthesis, characterization, and application of a novel azo-linked compound, E)-4-(5-((8-hydroxyquinolin-5-yl) diazenyl)-1, 3, 4-thiadiazol-2-yl) benzoic acid, for application in textile research. The synthesized compound was characterized using FT-IR, ?H NMR, and ??C NMR spectroscopy, confirming the presence of key functional groups such as the azo (-N=N -) and thiadiazole moieties. Moreover, This study investigated the color fastness of as prepared dye on three different fabric types: cotton, polyester, and silk. Fastness properties, including washing, light, and rubbing fastness, were evaluated under various conditions, such as washing with detergent, alkaline (NaOH), and acidic (HCl) solutions. Polyester exhibited superior fastness across all tests, showing high stability and color retention. Silk displayed good resistance in neutral and acidic environments but was sensitive to alkaline conditions. Cotton demonstrated lower fastness, particularly in alkaline conditions, indicating its susceptibility to dye leaching. The findings highlight polyester?s durability and suitability for use in environments demanding high fastness.
