Perfume compound (5)
I believe the answer is:
ester
'perfume compound' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ester that I've seen before include "Compound formed from acid and alcohol" , "Compound; trees (anag.)" , "Chemical compound of acid and alcohol, found in trees" , "radical" , "Organic chemical compound" .)
