| | 2-Bromopropionic acid Usage And Synthesis |
| Chemical Properties | clear colorless to yellowish liquid after melting. soluble in water, miscible with alcohol, ether, chloroform and benzene. | | Uses | It is employed as pharmaceutical and agrochemical intermediate. It is used as an alkylation agent for mercaptans and other sulfur containing compounds. | | Uses | 2-Bromopropionic Acid is a versatile reactant used in emulsion polymerization in the preparation of reversible addition-fragmentation chain transfer (RAFT) agent. | | Application | 2-bromopropionic acid is an organic synthesis intermediate, used in the production of herbicides quizalofop-ethyl, napropamide, fenthiaprop and fungicides metalaxyl, benalaxyl, procymidone, etc., used in the synthesis of pharmaceutical intermediates body alanine. | | Preparation | 2-Bromopropionic acid is obtained by bromination of propionic acid. Add propionic acid and phosphorus trichloride to the reaction kettle, keep the temperature at 80°C, slowly add bromine to the reaction solution dropwise, and heat up to 85°C after the addition of bromine, and raise the temperature to 100°C when the color of bromine disappears completely, it takes about 2~3h, and then the bromine and hydrobromic acid are recovered under reduced pressure, and then the finished product is obtained by distillation under reduced pressure. | | Synthesis Reference(s) | Tetrahedron Letters, 13, p. 4067, 1972 DOI: 10.1016/S0040-4039(01)94239-X |
