WebBinary ethyleneimine (BEI) is an aziridine compound, produced from bromoethylamine hydrobromide (BEA) commonly used for the inactivation of FMD virus during vaccine … Binary ethylenimine (BEI) is a preparation of aziridine. It can be produced by heating bromoethylamine hydrobromide or 2-aminoethyl hydrogen sulfate in the presence of sodium hydroxide (Gabriel method). It contains at least one three-membered ring which is very reactive because of the ring strain. It is used to … See more BEI is very hazardous since it attacks nucleic acids and proteins as described above. It can be neutralised by sodium thiosulfate; the thiosulfate is a nucleophile which opens the three-membered ring. The presence of … See more • Bahnemann, H. G. (1976).
