Other names :
1,3-benzodioxole-5-carbaldehyde ; 3,4-dihydroxybenzaldehyde methylene ketal ; 3,4-dimethylene dioxybenzaldehyde ; Dioxymethylene procatechuic aldehyde ; Dioxymethylene protocatechuic aldehyde ; 5-formyl-1,3-benzodioxole ; Geliotropin ; Heliobase ; 3,4-methylene dioxy benzaldehyde ; 3,4- methylene dioxybenzaldehyde ; 3,4- methylenedioxybenzaldehyde ; Piperonal ; Piperonaldehyde ; Piperonyl aldehyde
Volatility :
Base
Uses in perfumery :
Heliotropin is used in carnation, mimosa, tuberose, frangipani, ambery and fougere notes. Stable in soap bases, but may be responsible for coloration in cosmetic products. Tends to be gradually replaced by Heliotropex® (base), because heliotropin is regulated on importation beyond certain quantities.
Natural availability :
Heliotropin is present in trace amounts in a natural state in Vanilla Bourbon Absolute, from which it can be extracted.
Year of discovery :
Discovered in 1869.
Other comments :
In comparision to Vanillin, Heliotropin has a caracteristical anisic and almond note.
Price Range :
€€
Stability :
Stable in perfumes and diverse functional bases

Synthesis route :
Heliotropin can be synthesized in several ways. A first method starts with Isosafrole (derived from Safrole, isolable from various essential oils) as it is capable of undergoing an oxidation with chromium salts and oxygen or ozone, to obtain Heliotropin. A second synthetic route uses Catechol, converted to 3,4-dihydroxymandelic acid by reaction with glyoxylic acid, in the presence of aluminium oxide. An oxidation followed by a decarboxylation allows to obtain a final intermediate product, capable of undergoing a reaction with dichloromethane in order to form the acetal function of the molecule (among other things), in the presence of quaternary ammonium salts.
Synthesis precursor :
Heliotropin is stored in lockers, as it is a precursor for the synthesis of MDA (methylenedioxyamphetamine).
Isomerism :
Heliotropin does not have any isomer used in perfumery.
