产品说明 一般描述 Methyl 2,5-dihydroxybenzoate (methyl gentisate) is an alkyl ester of gentisic acid. It is reported to show less cytotoxic and mutagenic activity than hydroquinone with a potential to inhibit melanogenesis. It has been synthesized from 2,5-dihydroxybenzoic acid. The crystal structure of the molecule was found to be planar. 应用 Methyl 2,5-dihydroxybenzoate (methyl gentisate) may be used as a starting material in the synthesis of euonyminol. 包装 25 g in glass bottle 基本信息 | 线性分子式 | (HO)2C6H3CO2CH3 | | 分子量 | 168.15 | | EC 号 | 218-427-8 | | MDL编号 | MFCD00016464 | | PubChem化学物质编号 | 24866683 | | NACRES | NA.22 |
