Sweet caramel fenugreek, maple sugar, burnt sugar, coffee
These share the same CAS number (28664-35-9) — the same core molecule sold under different trade names. They're close to interchangeable, but purity and isomer ratio can cause subtle differences in strength and character, so treat them as near-identical rather than exactly the same.
This can happen for very unique materials that have no close olfactory equivalents in the database. Try searching for a related material instead.
