O-phenanthroline with CAS number 66 - 71 - 7 is a heterocyclic organic compound. It is a white to off - white crystalline powder with a molecular formula of C₁₂H₈N₂ and a molecular weight of approximately 180.20 g/mol. This compound is sparingly soluble in water but soluble in common organic solvents such as ethanol, methanol, and chloroform.
The high - quality O - phenanthroline we offer is synthesized using advanced chemical processes, ensuring high purity and stability. With strict quality control, the purity of our product can reach over 99%, which makes it suitable for a wide range of applications in various industries.
1. Analytical Chemistry: O - phenanthroline is widely used as a chelating agent in analytical chemistry. It forms stable complexes with metal ions such as iron(II), copper(II), and zinc(II). These complexes often have characteristic colors, which can be used for the photometric determination of metal ions in solution. For example, the red - colored complex formed with iron(II) is commonly used in the quantitative analysis of iron in samples.
2. Coordination Chemistry: In coordination chemistry, it serves as a ligand to form coordination compounds with various metal centers. These coordination compounds have unique electronic and magnetic properties, which can be applied in the fields of catalysis, materials science, and supramolecular chemistry.
3. Biological Research: O - phenanthroline has shown potential in biological research. It can interact with DNA and proteins, and some of its metal complexes have antibacterial and anticancer activities. For instance, copper - o - phenanthroline complexes have been studied for their ability to induce apoptosis in cancer cells.
1. Preparation of Solutions: First, choose an appropriate solvent according to your experiment requirements. If you need an aqueous solution, you can use a small amount of a co - solvent (such as ethanol) to help dissolve the O - phenanthroline. Add the solid O - phenanthroline slowly to the solvent under stirring until it is completely dissolved.
2. Complex Formation: When using O - phenanthroline for metal ion complexation, add the solution of O - phenanthroline to the solution containing the target metal ion. Adjust the pH of the solution if necessary, as the formation of complexes is often pH - dependent. Stir the mixture gently for a certain period to ensure complete complexation.
3. Analytical Procedures: In photometric analysis, measure the absorbance of the metal - O - phenanthroline complex at the appropriate wavelength using a spectrophotometer. Compare the absorbance value with a standard curve to determine the concentration of the metal ion in the sample.
1. Iron Determination in Water Samples: A water treatment plant needed to accurately determine the iron content in its raw water. The analysts used O - phenanthroline as a chelating agent. They first filtered the water sample to remove any suspended solids. Then they added an appropriate amount of acid to adjust the pH and added hydroxylamine hydrochloride to reduce iron(III) to iron(II). After that, they added O - phenanthroline solution. The red - colored iron(II) - o - phenanthroline complex was formed, and its absorbance was measured at 510 nm. By comparing with a standard curve prepared with known iron concentrations, the iron content in the water sample was accurately determined. This information helped the plant to optimize its water treatment process.
2. Catalytic Application: A research group in a chemical laboratory was studying a new catalytic reaction for the synthesis of a pharmaceutical intermediate. They used a copper - o - phenanthroline complex as a catalyst. They found that under mild reaction conditions, the reaction rate was significantly increased, and the yield of the target product was improved. The unique electronic structure of the copper - o - phenanthroline complex was thought to play a crucial role in activating the reactants and facilitating the reaction pathway.
