Description

4-(2-pyridylazo)resorcinol, also known as PAR, is a chelating agent commonly used in analytical chemistry. It forms intensely colored complexes with various metal ions, making it useful for spectrophotometric determination of metals like iron, copper, cobalt, and nickel. PAR is synthesized by diazotization of 2-aminopyridine followed by coupling with resorcinol. The resulting azo dye exhibits high selectivity and sensitivity for metal ions, particularly in alkaline conditions. Its importance lies in its ability to provide a simple, rapid, and sensitive method for metal analysis in diverse samples, including environmental, biological, and industrial matrices. Researchers study PAR due to its versatility in analytical applications, its ability to form stable complexes with various metal ions, and its potential for development of new and improved analytical methods.'
