Veratrumaldehyde ( 3,4-dimethoxybenzaldehyde ) is a derivative of both benzaldehyde and veratrole ( o -dimethoxybenzene). It can also be viewed as methyl vanillin .
It can be obtained from veratrole by formylation with N-formylpiperidine and phosphorus oxychloride , as well as by means of Vilsmeier formylation .
use
By reacting veratrumaldehyde with malonic acid , 3,4-dimethoxycinnamic acid can be prepared .
