Benzenemethanol, 3,4,5-trimethoxy- - Reference Information
| application | 3,4,5-trimethoxybenzyl alcohol is a commonly used pharmaceutical intermediate, which can be used to synthesize polyhydroxystilbene compounds with anti-tumor and anti-aging activities. |
| preparation | 3,4,5-trimethoxybenzaldehyde 2.729g and sodium borohydride 0.459g are dissolved in 20ml of methanol, stirred for 30min at room temperature, adjusted to pH 8-9 with dilute hydrochloric acid, extracted with chloroform (10ml × 2), after the organic phase is combined, it is washed with water (10ml × 2), dried by anhydrous magnesium sulfate and filtered, and the filtrate is evaporated to remove the solvent to obtain 2.61g of oily 3,4, 5-trimethoxybenzyl alcohol with a yield of 95%. |
| Use | Used as an intermediate in organic synthesis Organic intermediate. |
