overview	4-methoxy-2-nitroacetanilide can be used as an intermediate in pharmaceutical synthesis. If 4-methoxy-2-nitroacetanilide is inhaled, please move the patient to fresh air; if the skin is in contact, remove the contaminated clothing, rinse the skin thoroughly with soapy water and clear water, and if you feel uncomfortable, seek medical attention;
use	used in the production of dyes and drugs.
production method	obtained by nitration of p-methoxyacetanilide. Chlorobenzene, p-methoxyacetanilide and a little sodium bisulfite are put into the nitrification reaction pot, the temperature is adjusted to 28 ℃, and 61% nitric acid is added within 4 hours. 3/5 is added at the beginning of 2h, 2/5 is added at the end of 2h, the reaction temperature is controlled at 25-30 ℃, and a little sodium bisulfite is added every hour during the feeding process. After addition, the reaction continued at 25-30 ℃ for 1.5h. After adding water and standing, the upper acid water is removed to obtain a chlorobenzene solution of 4-methoxy-2-nitroacetanilide, and the finished product is obtained after desolution.
