mixture of 50–80% cis-isomers 4-hydroxy-3-[(1RS,3SR)-1,2,3,4-tetrahydro-3-{4-[(α,α,α-trifluoro-p-tolyl)methoxy]phenyl}-1-naphthyl]coumarin and 50–20% trans-isomers 4-hydroxy-3-[(1RS,3RS)-1,2,3,4-tetrahydro-3-{4-[(α,α,α-trifluoro-p-tolyl)methoxy]phenyl}-1-naphthyl]coumarin
CAS name: 4-hydroxy-3-[1,2,3,4-tetrahydro-3-[4-[[4-(trifluoromethyl)phenyl]methoxy]phenyl]-1-naphthalenyl]-2H-1-benzopyran-2-one
CAS Reg. No.: 90035-08-8
Formula: C33H25F3O4
Activity: rodenticides (coumarin rodenticides)
Notes: This substance was originally defined as a mixture of 40–60% cis-isomers and 60–40% trans-isomers, but the manufacturer (BASF) later requested that the definition be changed to reflect the composition of the commercial product, which contains a mixture of 50–80% cis-isomers and 50–20% trans-isomers, and the definition was updated in December 2008.
