chemical properties crystalline compound. The melting point is greater than 50°C.
Use Verapamil intermediate.
production method using guaiacol as raw material, methylation with dimethyl sulfate under the action of sodium hydroxide to generate o-dimethoxybenzene, and then chloromethylation with formaldehyde and concentrated hydrochloric acid to obtain 3, 4-dimethoxybenzyl chloride, the latter is heated with sodium cyanide, and dimethoxybenzonitrile is obtained after cyanidation, then it is condensed with bromoisopropane with sodium hydroxide (isopropylation) to produce the product.
