2,3-DIHYDROXYQUINOXALINE Chemical Properties,Usage,Production
Chemical Properties
off-white powder
Uses
2,3-Dihydroxyquinoxaline is a fluorescent reagent and it can be used for the determination of trace Pb(II) in vinegar.
Application
2,3-Dihydroxyquinoxaline can be used:
(1) Basic chemical studies to determine the low-temperature x-ray molecular structure, reciprocal isomerism and spectroscopic properties of 2,3-Dihydroxyquinoxaline[1].
(2) Quinoline-5-carboxamide derivatives (Vq-Vu) and (VIa-Vu) were prepared by using methyl 2,3-diaminobenzoate as raw material[2].
General Description
2,3-Dihydroxyquinoxaline(dhq) undergoes electrophilic substitution reaction with sulphuric acid solution and potassium nitrate to form 2,3-dihydroxy-6-nitroquinoxaline. It reacts with Ru3(CO)12 in DMSO to give the Ru(CO)2(dhq)(DMSO) complex.
