Description and Uses

6-Methylchromone-2-carboxylic acid is a chromone derivative. Chromones are cyclic compounds containing nine carbon atoms with sp² hybridization. They are commonly referred as 1,4-benzapyranes or γ-benzopyrones. Its energy of combustion was measured by an isoperibolic micro-combustion calorimeter. Standard molar enthalpy of formation derived from the energy of combustion, for 6-methylchromone-2-carboxylic acid was reported to be -(656.2 ± 2.2)kJmol^-1.
