Chemical Properties
Light Tan Cyrstalline Solid
Uses
3-Hydroxy-4-methoxybenzaldehyde was used as starting reagent during the two-step stereoselective synthesis of the anticancer drug (Z)-combretastatin A-4 and glycitein synthesis.
Application
Isovanillin is a kind of fragrance and isomer of vanillin. it has unique properties than vanillin, its fragrance can change with the change of ambient temperature, so it is especially suitable for special cosmetics and some special fragrance industries. Isovanillin is a selective inhibitor of aldehyde oxidase. It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid, which could make it a candidate drug for use in alcohol aversion therapy.
Preparation
Synthesis of isovanillin: 4-Hydroxybenzaldehyde is used as raw material, firstly react with bromine to obtain 3-bromo-4-hydroxybenzaldehyde, then react with methyl iodide to obtain 3-bromo-4-methoxybenzaldehyde, and then hydrolyzed under the action of sodium hydroxide and cuprous chloride to produce isovanillin. The yield was 64.1%.
Definition
ChEBI: Isovanillin is a member of the class of benzaldehydes that is 4-methoxybenzaldehyde substituted by a hydroxy group at position 3. It is an inhibitor of aldehyde oxidase. It has a role as an EC 1.2.3.1 (aldehyde oxidase) inhibitor, a plant metabolite, an antidiarrhoeal drug, an antifungal agent, a HIV protease inhibitor and an animal metabolite. It is a member of phenols, a monomethoxybenzene and a member of benzaldehydes.

General Description
3-Hydroxy-4-methoxybenzaldehyde on condensation with furan-2-carboxylic acid hydrazide and thiophene-2-carboxylic acid hydrazide yields Schiff-bases. It undergoes condensation reaction with1-azabicyclo[2.2.2]octan-3-one to give (Z)-2-(3-hydroxy-4-methoxybenzylidene)-1-azabicyclo[2.2.2]octan-3-one.
