Product Information
2,3-Dimethyl-6-nitroquinoxaline (DMNQ) is a synthetic quinoxaline. It is used as an analytical reagent in the detection of chloride ions by chromatography. DMNQ reacts with chloride ions to produce a red chromophore that can be detected at 540 nm. The reaction rate depends on the nature of DMNQ and the acid catalyst used, and the reaction time is dependent on the concentration of DMNQ and the acid catalyst used in solution. DMNQ has functional groups that allow it to react with chloride ions to form a chromophore (formula: Cl + DMNQ → Cl-C=O). The DMNQ molecule has two dihedral angles, which are rotations around an axis connecting two atoms or groups of atoms. These dihedral angles are important because they determine how well DMNQ can rotate around this axis, which affects its reactivity.
