Phenol and millon's reagent reaction
Web2. apr 2024 · Salicyclic acid and other phenolic compounds give positive reaction with this test. Chloride interferes with this reaction, hence the test cannot be done in chloride containing samples like urine. The proteins, on the addition of Millon’s reagent, form a white precipitate first due to denaturation of proteins by mercury salts, References: http://biocheminfo.com/2024/04/02/millons-test-principle-reaction-reagents-procedure-and-result-interpretation/
Phenol and millon's reagent reaction
Did you know?
http://biocheminfo.com/2024/04/02/millons-test-principle-reaction-reagents-procedure-and-result-interpretation/ WebBecause the grignard reagent acts as a carbanion (have two lone pair of electrons on a carbon), it is highly reactive and a strong nucleophile. Because of this, if we were to use water as our solvent, which contain hydrogens that are easy to steal by the carbanion, we would lose our grignard reagent and can no longer complete the reaction.
WebMillon's reagent is an analytical reagent used to detect the presence of soluble proteins. A few drops of the reagent are added to the test solution, which is then heated gently. A reddish-brown coloration or precipitate indicates the presence of tyrosine residue which occur in nearly all proteins.
