|  |  | 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.
