1-(2-thiazolylazo)-2-naphthol, also known as 2-(2-thiazolylazo)-1-naphthol or TA-N, is a heterocyclic organic compound that is widely used as a chromogenic reagent in analytical chemistry. TA-N is synthesized by the reaction of 2-aminothiazole with 1-nitroso-2-naphthol. It forms colored complexes with a variety of metal ions, making it useful for spectrophotometric determination of metals like copper, nickel, cobalt, and iron. The color change upon complexation is highly sensitive and allows for quantitative analysis of trace metals. The sensitivity of TA-N to metal ions makes it a valuable tool in environmental monitoring, food safety, and industrial process control.'
