Bergamot acetoacetate has no known scent.
Luebke, William tgsc, (1987): Fresh herbal bergamot stem floral buchu
Fraterworks: Neobergamate forte is a little known fresh top note chemical with a clear bergamot character but a floral and vaguely buchu and green stick heart. it has great potential as a non-allergenic material to use in place of bergamot oil when a more novel effect is wanted.
Citrus-like accords with linalool, dihydromyrcenol, coranol and linalyl acetate are excellent, but this material is also valuable for tea blends and other areas where a bolder bergamot note is needed.
