The molecule is a pyridine ring (six-membered aromatic ring with one nitrogen). Number the ring with the nitrogen as position 1 and proceed clockwise.

- Position 2: a formyl group (-CHO) is attached.  
- Position 3: a trifluoromethoxy group (-OCF3): think of it as a methoxy group in which all three hydrogens on the methyl are replaced by fluorine atoms.
- Position 4: a bromine atom.  
- Position 6: a difluoromethyl group (carbon bonded to the ring carries two fluorines and one hydrogen).

There are no chiral centers or E/Z double bonds.
