1,4-Dihydroxynaphthalene Chemical Properties,Usage,Production

Chemical Properties

brown to greyish powder. 1,4-Naphthalenediol [571-60-8], mp 195℃, is synthesized by reduction of 1,4- naphthoquinone with sodium dithionite, or by hydrolysis of 4-amino-1-naphthol with 20 % sulfuric acid. It undergoes oxidation to give 1,4-naphthoquinone; amination to give 4-amino-1-naphthol; and methylation (MeOH – HCl) to give 4-methoxy-1-naphthol.

Uses

1,4-Dihydroxynaphthalene is frequently used in organic synthesis as a reagent. In particular, it is used in the synthesis of a pH independent and cell permeant fluorescent dye, a hydroxyl regioisomeric 3'',4''-benzorhodol, which can be used as a fluorescent chemosensor and biomarker for biological applications.

Definition

ChEBI: Naphthalene-1,4-diol is a naphthalenediol and a naphthohydroquinone.
