Precision and reliability are paramount in analytical chemistry. The accurate quantification of metal ions is crucial across various sectors, including environmental monitoring, quality control, and industrial process management. 1,10-Phenanthroline Monohydrochloride (CAS: 3829-86-5) is a well-established and highly effective reagent for achieving these objectives, particularly in photometric determinations.

The Power of Complexation in Analysis

1,10-Phenanthroline Monohydrochloride is a bidentate ligand that forms stable, intensely colored complexes with many metal ions. This property is the basis for its widespread use in spectrophotometric analysis. The principle involves reacting a sample containing metal ions with the phenanthroline derivative. The resulting colored complex absorbs light at a specific wavelength, allowing for its concentration to be determined using a spectrophotometer. The intensity of the color is directly proportional to the concentration of the metal ion in the sample.

Key Analytical Applications:

  • Ferrous Iron Determination: Perhaps its most classic application, 1,10-Phenanthroline Monohydrochloride forms a vibrant red complex with Fe(II) ions, enabling sensitive and accurate quantification even at low concentrations. This is vital for water analysis and metallurgical testing.
  • Copper and Zinc Quantification: It also exhibits strong complexation with Cu(I), Cu(II), and Zn(II), making it a valuable reagent for determining these metals in various matrices.
  • Masking Agents: In complex samples, phenanthroline derivatives can sometimes be used as masking agents to prevent interference from other metal ions during analysis.
