The standard molar enthalpy of formation for dimethyl 2,6-pyridinedicarboxylate has been calculated from the standard molar enthalpy of combustion, which was measured by a static bomb calorimeter.It may be used in the synthesis of: . ditopic macrocycle having two xylyl rings linked by diethylene glycol and 2,6-pyridinediamide spacers, which acts as host molecule capable of forming complexes with diphenylurea derivatives . N,N′-bis(2-aminoethyl)dipicoloinic acid diamide Schiff base . 1,1′-(2,6-bispyridyl)bis-3-(9-ethylcarbazole-3-yl)-1,3-propanedione The standard molar enthalpy of formation for dimethyl 2,6-pyridinedicarboxylate has been calculated from the standard molar enthalpy of combustion, which was measured by a static bomb calorimeter.
