use | can be used to synthesize iodophthalamide, a diagnostic drug. The drug is also called new panophores and can be used for cardiovascular angiography, abdominal aortography, pyelography, and cerebral angiography. Dimethyl 5-nitroisophthalic acid is a useful chemical reagent in organic synthesis, used as an intermediate in organic synthesis. |
Production method | It is obtained by esterification of 5-nitroisophthalic acid ([618-88-2]) and methanol in the presence of sulfuric acid. Add 5-nitroisophthalic acid, methanol and sulfuric acid into the reaction pot, stir and heat, and reflux for 7 hours. Discharging, cooling and filtering. The filter cake is washed with distilled water and dried to obtain dimethyl 5-nitroisophthalic acid. 90% yield. |
