Bioallethrin is the ISO common name for an

allethrin in any ratio.
''Esbiothrin'' (
CAS number ) is a mixture of the same two stereoisomers, but in an approximate ratio of ''R'':''S'' = 1:3.
''Esbioallethrin'' or ''S-bioallethrin'' (
CAS number ) is the pure ''S''-form (that is, the wedge in the structure as shown in the box points down).
The name bioallethrin was a common name approved by the British Standards Institution and published in. BS 1831 has been withdrawn, and the common name has been adopted by ISO. It is also included in
