How Dihydrojasmone differs from similar materials

cis-Jasmone*

A reference describes dihydrojasmone's jasmine as resembling natural cis-jasmone; cis-jasmone is greener, with celery seed and tea, dihydrojasmone fruitier and woodier. (compared directly by a cited source)

An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
