2,3,4-Trimethoxybenzaldehyde Usage And Synthesis
| Description | 2,3,4-Trimethoxybenzaldehyde is a white crystalline powder, and the chemical formula is C 10H 12O 4; the molecular weight is 196.2; the fusing point is 38-40 degrees, and is a kind of important medicine intermediate; it is mainly used in new type drug Ca2+ Synthesizing of channel blocker. The alternative cerebral arteries that are used for this medicine reduce the headache incidence, mainly for the preparation of the intermediate of trimetazidine. |
| Synthesis | A coking gallic acid is utilized as a raw material, and dimethyl sulfate is utilized as an alkylate reagent; under the condition of the existence of sodium hydroxide, methylation is performed through an O-alkylation reaction to obtain an intermediate 1, 2, 3-trimethoxybenzene. After that, the 1,2, 3-trimethoxybenzene and a Vilsmeier-Haack reagent are subjected to a formylation reaction to get the 2,3,4-Trimethoxybenzaldehyde. |
| Chemical Properties | white to light yellow crystals or cryst. powder |
| Uses | 2,3,4-Trimethoxybenzaldehyde is a trimethoxylated aromatic aldehyde. 2,3,4-Trimethoxybenzaldehyde is an Impurity of the anti-anginal drug Trimetazidine (T795610). |
| Uses | 2,3,4-Trimethoxybenzaldehyde was used to study the effects of 2,3,4-trimethoxybenzaldehyde on tubulin-dependent GTP hydrolysis. |
