| | Ethyl bromopyruvate Usage And Synthesis |
| Chemical Properties | Clear yellow to pink-red liquid | | Uses | Ethyl 3-bromopyruvate is employed in a synthesis of thioxothiazolidines from primary amines and carbon disulfide. | | Uses | Employed in a synthesis of thioxothiazolidines from primary amines and carbon disulfide.1 | | Hazard | Severe poison, lachrymator, irritant. | | Purification Methods | The most likely impurity is free acid (bromopyruvic or bromoacetic acids). Dissolve the ester in dry Et2O or dry CHCl3, stir with CaCO3 until effervescence ceases, filter, (may wash with a little H2O rapidly), dry (MgSO4) and distil it at least twice. The 2,4-dinitrophenylhydrazone has m 144-145o. [Burros & Holland J Chem Soc 672 1947, Letsinger & Laco J Org Chem 21 764 1956, Kruse et al.
