2,4-Dinitrophenylhydrazine
2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C6H3(NO2)2NHNH2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.
Примеры употребления для 2,4-D
1. Chemical sprays that included 2,4 D were put on the market for use in controlling weeds in yards and along roads and railroads.
2. Its flagship product is a herbicide called 2,4–D, which was first invented in 1'42 and is used worldwide to whack weeds.
3. During World War II, Prof Kraus, Chairman of the Department of Botany at the University of Chicago, discovered that a chemical named 2,4 D could kill vegetation within 24–48 hours by causing plants to experience sudden, uncontrolled growth.
4. Makhteshim anticipates growing demand for the chemical because of the widening proliferation of crop seeds engineered to be 2,4–D resistant, meaning the herbicide will kill the weeds but not the crop.
5. The US Army continued to experiment with 2,4 D during the 1'50‘s and late in the decade, they found that mixing it with another chemical resulted in the creation of an herbicide that had an almost immediate toxic effect on foliage.
