The molecule is a para-substituted stilbene, consisting of two benzene rings joined by a -CH=CH- vinyl bridge (no E/Z stereochemistry specified).

Ring A (first benzene): at the para position relative to the vinyl bridge, the ring carbon bears an ethoxy substituent, in which an oxygen atom bonded to the ring is connected to an ethyl group.

Ring B (second benzene): at the para position relative to the vinyl bridge, the ring carbon bears a carbamic acid substituent. This group consists of a nitrogen atom directly bonded to the benzene ring; the nitrogen is also bonded to a carboxylic acid group.
