Hazard InformationBack Directory
[Hazard]

Severe poison, lachrymator, irritant.
[Chemical Properties]

Clear yellow to pink-red liquid
[Uses]

Employed in a synthesis of thioxothiazolidines from primary amines and carbon disulfide.1
[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.
