A powerful floral-aldehydic aroma chemical reminiscent of hawthorn blossom and mimosa, with a green, waxy, slightly anisic facet. Develops a soft powdery-floral character on the dry down, often compared to cyclamen aldehyde but heavier and more tenacious.AI · claude-opus-4-7

Colorless viscous liquid.
Practically insoluble in water, soluble in alcohol and oils.
Heavy green, twig-like odor, also bark- or sap-like with a fruity undertone.
Has been suggested as a green modifier where the green notes should be more woody, barklike, less foliage-like. Interesting in Lilac, Rose and even in non-floral fragrance types (Chypre, etc.).
Produced from para-tertiary-amyl phenol in weak NaOH plus Monochlordimethylacetal to make the Acetal. Oxalic acid hydrolysis will yield the Aldehyde.
