Description and Uses

2,6-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.

2,6-Diaminopyridine, used as a pharmaceutical intermediate and a hair dye coupler in oxidation/permanent formulations.
