Extraction and presentation
Anilofos can be prepared from 1,4-dichlorobenzene and isopropylamine , which react to p -chloro- N -isopropylaniline. p -Chlor- N -isopropylaniline reacts further with chloroacetic acid chloride and dimethyldithiophosphoric acid (DMPA) to form anilofos.
use
Anilofos was used as a selective herbicide under the trade names Arozin and Rico , especially in rice cultivation.
