Reading about inhalational agent today & come across this thing BCDFE :)
Well, it's the breakdown product of Halothane... (It would be more special if the name is BCDEF)
Degradation of Halothane in soda lime will give rise to vinyl compound, known as 2-Bromo, 2-Chloro, 1,1-DiFluoroEthane (also known as BCDFE)
at least this is easier to remember than breakdown product of Sevoflurane..
Degradation of Sevoflurane in soda lime will give rise to vinyl ether compound, also known as Compound A or Pentafluoro Isopropenyl Fluoromethyl Ether (or PIFE). *Pening* to remember this long "organic chemical" name..
