Why is vanillin not completely soluble in water?
Vanillin. Vanillin has a soothing, pleasant aroma. Its molecular weight is relatively low, and it is fairly volatile. Molecules containing only carbon and hydrogen are mostly insoluble in water.
Is vanillin a liquid or solid?
Vanillin, as its name implies, is the major flavor component of vanilla. The three oxygen atoms in this small aromatic compound are in different functional groups: alcohol, aldehyde, and ether. It is a white crystalline solid with a melting point of 81–83 ºC.
What is the chemical properties of vanillin?
Chemical Properties Vanillin is a colorless, crystalline solid (mp 82–83°C) with a typical vanilla odor. Because it possesses aldehyde and hydroxy substituents, it undergoes many reactions. Additional reactions are possible due to the reactivity of the aromatic nucleus.

Is vanillin a secondary metabolite?
As a plant secondary metabolite, natural vanillin is extracted from the seedpods of orchids (Vanilla planifolia, Vanilla tahitensis and Vanilla pompona). Phytochemicals such as ferulic acid are the major substrates used in natural vanillin production methods.
What is more volatile vanillin and Zingerone?
The higher molecular weight of zingerone in combination with the polar side-chain carbonyl group makes zingerone molecules attract each other more strongly than eugenol and vanillin molecules do. As a result, zingerone is less volatile than either eugenol or vanillin.
