IUPAC: 3-[(1RS,3RS;1RS,3SR)-3-(4′-bromobiphenyl-4-yl)-3-hydroxy-1-phenylpropyl]-4-hydroxycoumarin
CAS: 3-[3-(4′-bromo[1,1′-biphenyl]-4-yl)-3-hydroxy-1-phenylpropyl]-4-hydroxy-2H-1-benzopyran-2-one

Formula: C30H23BrO4
Activity: rodenticides (coumarin rodenticides)
Notes: When the name bromadiolone was approved, no information on the proportions of the 4 stereoisomers was provided, and the name has been assumed to apply to any mixture of stereoisomers. It is now known that bromadiolone has always comprised a mixture of ≥ 80% (1RS,3SR)-isomer and ≤ 20% (1RS,3RS)-isomer, and the definition will be updated when ISO 1750 is revised.
The mixture of ≥ 80% (1RS,3RS)-isomer and ≤ 20% (1RS,3SR)-isomer has its own ISO common name, alpha-bromadiolone.
