2,3-Dichloroquinoxaline Chemical Properties,Uses,Production
Description
2,3-Dichloroquinoxaline (DCQX) can be used as a substrate for nucleophilic aromatic substitution (SNAr) reactions and is a versatile building block for the synthesis of many quinoxaline derivatives. 2,3-Dichloroquinoxaline reacts with 6-aminothiouracil in ethanol/TEA to form 6-amino-2-(3-chloroquinoxalin-2-ylthio)pyrimidin-4(3H)-one. It reacts with cholest-5-en-3-one semicarbazone/thiosemicarbazone to form steriodal cholest-5-en-3-oxazolo and thiazoloquinoxaline.
Chemical Properties
solid
Uses
2,3-Dichloroquinoxaline is a dichlorinated quinoxaline derivative with antimicrobial activity. 2,3-Dichloroquinoxaline is used in the preparation of quinoxaline derivatives of cancer chemopreventive a ctivity.
General Description
Gray solid. Insoluble in water.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A halogenated amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Fire Hazard
2,3-Dichloroquinoxaline is probably combustible.
Purification Methods
Recrystallise it from *C6H6 and dry it in a vacuum [Cheeseman J Chem Soc 1804 1955, Beilstein 23/7 V 144].
