We are the better twins.
You know who we are when you look at us?
I'm a 5,5'-oxy bis (5-methylene-2-furaldehyde) OBMF ether, and I'm just looking at our molecular formula. They also call us OBMF.
The etherification of 5,5'-oxy bis (5-methylene-2-furaldehyde) OBMF can be used as raw material to prepare polyamides and polyimides, and can also be used to synthesize heterocyclic ligands and hepatitis antiviral precursors. Don't look down on us!
