3,5-Dimethoxybenzoic acid Usage And Synthesis

Chemical Properties

almost white to light beige-pink cryst. powder

Uses

3,5-Dimethoxybenzoic acid (3,5-DmeoxBA) can be used as a reactant for the synthesis of:

  • 5,7-Dimethoxy-3,4-diphenylisocoumarin by coupling with diphenylacetylene.
  • Biotin dimedone, a reagent used in the study of protein sulfenation.

It can also be used as a ligand to synthesize lanthanide complexes [Ln(3,5-DmeoxBA)3(phen)]2; where phen is 1,10-phenanthroline.

Definition

ChEBI: 3,5-dimethoxybenzoic acid is a methoxybenzoic acid that is benzoic acid which is substituted by methoxy groups at positions 3 and 5. It has a role as a plant metabolite. It is a conjugate acid of a 3,5-dimethoxybenzoate.

Purification Methods

Crystallise the acid from water, EtOH or aqueous acetic acid and dry it in a vacuum. [Beilstein 10 H 405, 10 I 195, 10 III 1446, 10 IV 1501.]
