产品说明 一般描述 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. 包装 1 g in glass bottle 基本信息 | 经验(实验)分子式 | C11H8O4 | | 分子量 | 204.18 | | MDL编号 | MFCD00239435 | | PubChem化学物质编号 | 24866156 | | NACRES | NA.22 |
