We are the best twins

You know who we are when you look at us?

I'm a 5,5'-oxybis(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'-oxybis(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!
