A new 2-methyl-5-(3',4'-dihydroxyphenylazo-1')-1,3,4-thiadiazole compound was synthesized and its physicochemical properties were determined. It forms coloured chelates with ions Fe2+, Co2+, Ni2+, Cu2+ soluble in water, non-extractable by organic solvents. The ligand metal ratio in these complexes is 2:1. Keywords: 2-methyl-1,3,4-thiadiazole azodyes, synthesis, complex-forming with metal ions.
