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 80–100% (1RS,3SR)-isomer and 20–0% (1RS,3RS)-isomer, and the definition will be updated when ISO 1750 is revised.
The mixture of 80–100% (1RS,3RS)-isomer and 20–0% (1RS,3SR)-isomer has its own ISO common name, alpha-bromadiolone.
