UDMH is known to be miscible with the following wafer, benzene, triethyl benzene, toluene, kerosene, ethyl alcohol, isobutyl alcohol, n-butyl ether, n-amyl ether, n-hexyl ether, diethyl ether, petroleum ether, petroleum naphtha, n-heptane, n-hexane, n-octane, n-decane, n-dodecane, n-hexadecane, cyclohexane, 1,2-dimethyl cyclohexane, phenyl cyclohexane, n-tetradecane, trichloroethylene, dichloroethylene, perchloroethylene, 1,1,1-trichloroethane, triethyl amine, ethylenediamine, diethylene triamine, acetonitrile, aniline, cumene, tetra-hydronaphthalene, tetraethylene pentamine, ethylene glycol and hydrazine (Ref 4)... 

Amino-5-carboxypyrazine in anhydrous dimethylformamide with triethyl-amine and ethyl chloroformate and then diethyl glutamate and stirred at room temperature gave 2-amino-5-(l, 3 -diethoxycarbonylpropyl)carbamoylpyrazine (24) (1244). Similarly a mixture of 2-carboxypyrazine and triethylamine in methylene dichloride with ethyl chloroformate and morpholine gave 2-( -morpholinocarbonyl)-pyrazine (1351). 2-Carboxy-3-hydroxypyrazine refluxed with phosphorus tris(A-methylanilide) in toluene gave 2-hydroxy-3-(A-methyl-A-phenyIcarbamoyl)pyrazine (1055), and 2-hydroxy-3-(A -methyl-A -p-tolylcarbamoyl)pyrazine was prepared similarly (1055). Tetracarboxypyrazine heated with sulfur tetrafluoride (SF4) at 150° gave tetra(trifluoromethyl)pyrazine (899).
