Compound Q&A
Are there alternatives to 4,4'-((1E,1'E)-(3,3'-dichloro-[1,1'-biphenyl]-4,4'-diyl)bis(diazene-2,1-diyl))bis(5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one) (CAS: 3520-72-7) in synthesis?
Answer
![4,4'-((1E,1'E)-(3,3'-dichloro-[1,1'-biphenyl]-4,4'-diyl)bis(diazene-2,1-diyl))bis(5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one)](https://static.chemtradehub.com/structs/352/3520-72-7-88e1.webp "4,4'-((1E,1'E)-(3,3'-dichloro-[1,1'-biphenyl]-4,4'-diyl)bis(diazene-2,1-diyl))bis(5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one)")
There are alternatives to 4,4'-((1E,1'E)-(3,3'-dichloro-[1,1'-biphenyl]-4,4'-diyl)bis(diazene-2,1-diyl))bis(5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one) (CAS: 3520-72-7) in synthesis, such as using simpler aromatic compounds or analogs like 2,2'-((1E,1'E)-(3,3'-dichloro-[1,1'-biphenyl]-4,4'-diyl)bis(diazen-1-ylidene))bis(5-methyl-2-phenyl-1,3-dihydro-4H-pyrazol-4-one). These alternatives can offer similar properties while reducing complexity and potentially lowering cost and environmental impact.
