A Kinetic Investigation of Metal-Dipeptide Complex with Ninhydrin in the Absence and Presence of CTAB Micelles

Abstract

Introduction Formation of Ruhemann s purple is widely used to detect amino groups in simple organic compounds, proteins and peptides. For these purposes usually, a spray reagent is prepared in situ in a laboratory environment. A variety of commercial spray reagents are available and these contain ninhydrin, one or more metal ions and surfactants in aqueous and non-aqueous media. Such sprays are used for developing TLC plates and in detecting finger prints for forensic work. The response to these reagents depended upon its formulation and a quicker color development is essential especially for forensic work. The purpose of such formulations is to improve the response time of Ruhemann s color development. Therefore, reac

Cascade Processes with Micellar Reaction Media: Recent Advances and Future Directions

“…The micellar phase also affected the quantity of the intermediates. Overall, the analysis suggested that the surfactant had a co-operative effect of the formation of the imine intermediate [ 21 ]. A similar co-operative effect of the surfactant on the intermediate has been observed between CTAB and p -nitroacetophenone (detected via NMR studies) in the Morita-Baylis-Hillman reaction of ketones [ 22 ].…”
