Description and Uses
1,3-Dihydroxynaphthalene (1,3-DHN) is a multifunctional chemical reagent. Similar to resorcinol, it can be phosphorylated at room temperature using phosphotriamide, though its rate of diphosphorylation is lower. In addition, the 1,3-DHN molecule exhibits fluorescent properties, with absorption spectra peaking at 290 nm and 330 nm, while the emission spectrum shows a peak at 380 nm and a shoulder peak at 425 nm. Non-ionic surfactants significantly enhance the fluorescence intensity of 1,3-DHN, whereas the addition of cationic or anionic additives diminishes its fluorescence intensity.
Reagent for sugars, oils, and for glucuronic acid in urine: Forsyth, Nature 161, 239 (1948); Heyns, Kelch, Z. Anal. Chem. 139, 339 (1953).
