GHS Hazard Classification

Reported hazard statements	H312 (100%), H400 (100%)

Documented Uses

• Used as pre-plant herbicide for control of annual grasses and broad-leaved weeds in cotton, legumes, vegetables, and other crops; [HSDB]
• /SRP: Former use/ selective pre-plant soil incorporated control of many annual grass and broad leaf weeds in cotton, soya beans, groundnuts, peas, beans, safflowers, sunflowers, carrots, turnips, fennel, chickory, and in transported tomatoes, capsicums, aubergines, and brassicas.
• Herbicide; Not registered in US
• Dinitramine is produced by reaction of 2-amino-3,5-dinitro-4-chlorotrifluorotoluene with diethylamine.
• The 2,4-dihalo-3,5-dinitrobenzotrifluoride starting materials are readily prepared by nitration of the 2,4-dihalobenzotrifluoride with a mixture of fuming nitric and fuming sulfuric acids at a temperature below about 80 °C.
• Selective soil-herbicide, absorbed by the roots and shoots, with very little translocation to the stems and leaves, and slightly more to the roots.
