When vanillin (4-hydroxy-3-methoxybenzaldehyde) is treated with CH3CH2MgBr (methylmagnesium bromide), a product known as methyl vanillate or methyl-4-hydroxy-3-methoxybenzoate is formed. This product is an important intermediate in the production of many flavors and fragrances.
Methyl vanillate is a methyl ester, a type of compound where a hydrogen in an organic molecule is replaced by a methyl group (CH3). In this case, the methyl group is attached to the oxygen atom of the carbonyl group in the vanillin molecule. The reaction between vanillin and CH3CH2MgBr can be represented as follows:
Vanillin + CH3CH2MgBr → Methyl vanillate + MgBr2
The reaction is known as a Grignard reaction and is used to form carbon-carbon bonds. In this reaction, the Grignard reagent (CH3CH2MgBr) acts as a nucleophile, attacking the oxygen atom in the carbonyl group of vanillin. The resulting intermediate is then treated with water to form methyl vanillate.
Methyl vanillate is an important intermediate for the production of various flavors and fragrances. For example, it is used in the production of vanillin, ethyl vanillin (used in fragrances and flavors) and menthol (used in cosmetics, medicines and food). It is also used in the production of methyl salicylate (used as a flavoring agent and a fragrance).

Was vanillin found in nature or was it man made?
Vanillin is generated in nature via the vanillin bean, it can also be synthesised in the lab.
Is vanillin an alcohol or carboxylic acids?
Vanillin has an alcohol functional group and a carboxylic acid functional group.

Effect of vanillin in a human body.?
1. Vanillin helps to kill cervical cancer cells. 2. Diseases that damage the cells of nervous system or the brain, septic shock, inflammation (involve formation of reactive oxygen and nitrogen species that include peroxynitrite) can be stopped by Vanillin. → Vanillin stops the reactions between Peroxynitrite and Tyrosine (an amino acid needed to form dopamine).
Is there any difference between vanillin made synthetically and vanillin extracted from vanilla beans?

What is the equation for the reaction of CH3CH2MgBr with methanol?
CH4
What are the ingredients in vanillin?
vanillin bean
What is the equation for the reaction of CH3CH2MgBr with benzophenone and then ammonium chloride in H2O?
benzophenone, or diphenyl ketone, is a ketone. You might have known that when Grignard reagents react with ketones, the product is a tertiary alcohol. CH3CH2MgBr + (C6H5)2CO-----> CH3CH2(C6H5)2COH (a tertiary alcohol) The ammonium chloride solution merely dissolves this alcohol.
Is vanillin homogeneous?
Vanillin is a single compound, not a mixture.
Was vanillin found in nature or was it man made?
Vanillin is generated in nature via the vanillin bean, it can also be synthesised in the lab.
What is the chemical formula for Vanillin?
Vanillin, methyl vanillin, or 4-hydroxy-3-methoxybenzaldehyde, is an organic compound with the molecular formula C8H8O3
Why do people put vanillin extract in chocolate?
Because They Want It Taste Like Vanillin, They Want It Taste Chocolate And Vanillin At The Same Time.
How much alcohol is in ethyl vanillin?
Ethyl vanillin contains no ethanol (drinking alcohol).
How will you convert ethyl bromide in to propane?
Ethyl bromide react with Grignard reagentCH3-CH2-Br + CH3-Mg_Br
Is vanillin an alcohol or carboxylic acids?
Vanillin has an alcohol functional group and a carboxylic acid functional group.
What is solubility of vanillin in hot water?
Vanillin is extremely soluble in hot water. The solubility would depend on the amount of vanillin. For example, 539 g would make it the most soluble.
