What is 3-Methoxysalicylaldehyde?
Chemical properties
Pale yellow to brown low melting solid
The Uses of 3-Methoxysalicylaldehyde
A positional isomer of Vanillin. o-Vanillin is a more potent antioxidant than Vanillin.
The Uses of 3-Methoxysalicylaldehyde
o-Vanillin has been used to study the solvent-free reaction between o-vanillin and p-toluidine using NMR, DSC and XRD analysis. It was used in the synthesis of new ligand for Fe(III) and Al(lII). It is also used in the study of mutagenesis and as a synthetic precursor for pharmaceuticals.

Definition
ChEBI: A member of the class of benzaldehydes that is salicylaldehyde substituted by a methoxy group at position 3.
Hazard
ortho-Vanillin is harmful if ingested, irritating to eyes, skin and respiratory system, but has an unmistakable high LD50 of 1330 mg/kg in mice.
Biochem/physiol Actions
o-Vanillin induces DNA damage as detected by comet assay.
