2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
Dimethylamine is an organic compound with the formula (CH 3) 2 NH. This secondary amine is a colorless, flammable gas with an ammonia -like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%.
2-Propenoic acid, polymer with 2 p-propenamide, sodium salt / Copolymer of acrylamide and sodium acrylate: Friction Reducer 71050-62-9: 2-Propenoic acid, polymer with sodium phosphinate (1:1) No record 66019-18-9: 2-propenoic acid, telomer with sodium hydrogen sulfite: No record 107-19-7: 2-Propyn-1-ol / Propargyl alcohol: No record 51229-78-8
2-methyl-4-chlorophenol + ClCH 2 CO 2 H + base → MCPA + base·HCl (hydrochloric acid) By the end of 1941 it was clear to the Templeman group that MCPA was one of the most active compounds tested but other auxin herbicides including 2,4-D were also effective.
2,4-DB or 4-(2,4-dichlorophenoxy)butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad-leaf weeds in alfalfa, peanuts, soybeans, and other crops. Its active metabolite , 2,4-D , inhibits growth at the tips of stems and roots.
2 C 6 H 5 NH 2 → (C 6 H 5) 2 NH + NH 3. It is a weak base, with a K b of 10 −14. With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate [(C 6 H 5) 2 NH 2] + [HSO 4] − as a white or yellowish powder with m.p. 123-125 °C. [8] Diphenylamine undergoes various cyclisation reactions.
The simplest organic chloramine is N-chloromethylamine, CH3NHCl; [7] notable examples include N-chloromorpholine (ClN(CH 2 CH 2) 2 O), N-chloropiperidine, and N-chloroquinuclidinium chloride. [8] Chloramines are commonly produced by the action of sodium hypochlorite on secondary amines: R 2 NH + NaOCl → R 2 NCl + NaOH
C 6 H 4 (CO) 2 NH + RX + NaOH → C 6 H 4 (CO) 2 NR + NaX + H 2 O. The amine is commonly liberated using hydrazine: C 6 H 4 (CO) 2 NR + N 2 H 4 → C 6 H 4 (CO) 2 N 2 H 2 + RNH 2. Dimethylamine can also be used. [5] Some examples of phthalimide drugs include thalidomide, amphotalide, taltrimide, talmetoprim, and apremilast.
