| | 2,5-Dimethoxycinnamic acid Usage And Synthesis |
| Chemical Properties | yellow powder | | Uses | 2,5-Dimethoxycinnamic acid can be used as a pharmaceutical intermediate, and can be used in the synthesis of vasodilators such as cinnepazide. | | Preparation | Synthesis of 2,5-dimethoxycinnamic acid: 2,5-dimethoxybenzaldehyde, malonic acid and pyridine were added to 100ml three necks, piperidine was added at 90°C, refluxed for 2h, cooled to room temperature, and added 3mol/L hydrochloric acid, resulting in a large amount of white precipitate, suction filtration, the filter cake is washed with water, reconstituted with ethanol, after drying, 2,5-dimethoxycinnamic acid was obtained as pale yellow needle crystals. | | Definition | ChEBI: 2,5-Dimethoxycinnamic acid is a hydroxycinnamic acid. | | General Description | 2,5-Dimethoxycinnamic acid forms 1:1 molecular complex with 3,5-dinitrocinnamic acid. |
