Safety Profile
USE WITH AWARENESSWhat Does Cinnamic aldehyde-methyl anthranilate (Schiff base) Smell Like?
This Schiff base opens with a vibrant burst of cinnamon-spiced warmth, reminiscent of freshly baked apple pie. The heart reveals a surprising twist – a juicy, grape-like fruitiness from the methyl anthranilate moiety. As it dries down, the fragrance evolves into a soft, powdery-woody base with lingering honeyed undertones. The overall effect is like candied orange peel dipped in spiced syrup, with remarkable tenacity on skin.

Chemistry, Properties & Perfumer Guide
The Chemistry
Cinnamic aldehyde-methyl anthranilate Schiff base forms through condensation of cinnamaldehyde with methyl anthranilate, creating a nitrogen double bond (C=N) characteristic of Schiff bases. This structure exhibits unique stability compared to its parent aldehydes. The conjugated system allows for electron delocalization, contributing to both its color and odor properties. While not found in nature, its components occur widely – cinnamaldehyde in cinnamon bark and methyl anthranilate in Concord grapes.
