Summary
[edit]DescriptionMillion's Reagent 001.jpg |
English: Millon's reagent is a chemical reagent used in analytical chemistry to test for the presence of aromatic amines, especially phenols. Named after the French chemist Auguste Millon, this reagent is a solution of mercuric nitrate in nitric acid. It is commonly employed in colorimetric tests, where a color change indicates the presence of specific functional groups.
Millon's reagent is particularly known for its ability to produce a red or pink coloration when reacting with phenols, which are organic compounds containing a hydroxyl group (-OH) attached to an aromatic ring. The reaction involves the formation of complex compounds between the phenol and the mercuric nitrate present in the reagent. Despite its historical significance, Millon's reagent is less commonly used today due to concerns about the toxicity of mercury compounds. Modern alternatives with safer reagents have been developed for similar analytical purposes.English: Millon's reagent is a chemical reagent used in analytical chemistry to test for the presence of aromatic amines, especially phenols.
