For chemists and lab technicians, selecting the right analytical reagents is paramount to achieving accurate and reproducible results. Among the myriad of indicators available, 1-(2-Pyridylazo)-2-naphthol, commonly known as PAN, stands out as a highly effective compound for the determination of transition metals. This article delves into why PAN (CAS 85-85-8) is a staple in many analytical laboratories and how to procure it from reputable suppliers.

Understanding the Importance of PAN (CAS 85-85-8)

1-(2-Pyridylazo)-2-naphthol is a complex organic molecule that possesses a unique ability to form vividly colored chelates with a wide array of metal ions. This property makes it an excellent indicator in complexometric titrations. When a metal ion is titrated with a chelating agent like EDTA, PAN signals the endpoint by changing color, allowing for precise quantification of the metal present. Its utility extends to spectrophotometric analysis, where the colored chelates can be measured quantitatively using a spectrophotometer, providing sensitive methods for detecting trace metals. If you are looking to buy this crucial reagent, consider sourcing from a manufacturer with a proven track record in China.

Key Applications in Analytical Chemistry

The versatility of PAN makes it suitable for a broad spectrum of applications:

  • Titration of Various Metals: PAN is effective for the titration of metals such as copper, zinc, cadmium, nickel, cobalt, and many others. Its distinct color changes facilitate clear endpoint detection.
  • Spectrophotometric Determination: It serves as a reliable spectrophotometric reagent for the determination of metals like iron, vanadium, and uranium, even at low concentrations.
  • Quality Control: In industrial settings, PAN is used in quality control processes to ensure the correct metal content in raw materials, plating baths, and finished products.
