2,3-DIAMINONAPHTHALENE Usage And Synthesis
Chemical Properties colourless to white crystalline powder
Uses 2,3-Diaminonaphtaline (DAN) is used as a derivatisation-reagent for the determination of selenium at low detection limits.
Purification Methods Crystallise the diamine from water, or dissolve it in 0.1M HCl, by heating to 50o. After cooling, the solution is extracted with decalin to remove fluorescent impurities and centrifuged. [Beilstein 13 IV 346.]
