3-Methoxybenzaldehyde Chemical Properties,Uses,Production

Chemical Properties

clear pale yellow to yellow liquid. Soluble in ethanol, diethyl ether, and benzene; insoluble in water.

Uses

3-Methoxybenzaldehyde is used to prepare 3-(3-methoxy-phenyl)-1-phenyl-propenone by reaction with benzldehyde. It is used as an eluent for mono-13C isotopomers of vanillin in normal phase silica gel chromatography. It acts as an inhibitor of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) metabolism.

Definition

ChEBI: 3-methoxybenzaldehyde is a member of the class of benzaldehydes in which the hydrogen at position 3 of benzaldehyde has been replaced by a methoxy group. It has a role as a Brassica napus metabolite. It is a member of benzaldehydes and a monomethoxybenzene.

Preparation

3-Methoxybenzaldehyde is obtained by the reaction of m-hydroxybenzaldehyde and dimethyl sulfate.

Synthesis Reference(s)

Synthetic Communications, 24, p. 2011, 1994 DOI: 10.1080/00397919408010209

General Description

m-Anisaldehyde has significant antifungal activity against Candida sp., including the azole-resistant strains.

Safety Profile

Mutation data reported. Whenheated to decomposition it emits acrid smoke andirritating vapors.

Purification Methods

Wash it with saturated aqueous NaHCO3, then H2O, dry it with anhydrous MgSO4 and distil it under reduced pressure under N2. Store it under N2 in sealed glass ampoules. [Beilstein 8 IV 241.]
