응용 분야
개요2,6-Diaminopyridine is an important organic reagent with a wide range of uses. It can be used for fluorescence detection, 2,6-Diaminopyridine fluorescence method for the determination of certain aromatic primary amines. It can also be used to prepare 2,6-Diaminopyridine imprinted core-shell nanoparticles. A new method for the detection of diaminopyridine derivatives using molecularly imprinted electrochemical sensors has been established, which has been applied to the detection of 2,6-Diaminopyridine in hair dyes with good sensitivity and selectivity.
용도2,6-Diaminopyridine, used as a pharmaceutical intermediate and a hair dye coupler in oxidation/permanent formulations.
제조 방법
In a 600 mL autoclave equipped with a gas entrapment stirrer, a solution of 5 g CuI in 120 g aqueous ammonia (30% NH3 by weight) was added and mixed with 77 g ammonium acetate and 60 g of 2, 6-dichloropyridine. After purging with nitrogen, 24 g of liquid ammonia was added resulting in a pressure of about 150 psi (1.03 MPa). Subsequently, the reaction mixture was heated to 150°C for 8 h under stirring. Throughout the reaction, the pressure decreased from an initial pressure of 680 psi (4.69 MPa) to 450 psi (3.10 MPa). The reaction mixture was allowed to cool to room temperature, and the pressure was brought back to atmospheric pressure. Finally, 2,6-Diaminopyridine was obtained after purification.
