| 2,3-Dichlorobenzoic acid Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powder | | Uses | 2,3-Dichlorobenzoic acid is the key intermediate for antiepileptic drug Lamotrigine (L173250) and other pharmaceuticals for the treatment of central nervous system (CNS) disorders and disease. | | Uses | 2,3-Dichlorobenzoic Acid (Lamotrigine USP Related Compound B) is the key intermediate for antiepileptic drug Lamotrigine (L173250) and other pharmaceuticals for the treatment of central nervous system (CNS) disorders and disease. | | General Description | 2,3-Dichlorobenzoic acid is an intermediate metabolite of polychlorinated biphenyls (PCBs). | | Purification Methods | Aromatic acid impurities (to <0.05%) can be removed via the (±)--methylbenzylamine salt as described for 2,4-dichlorobenzoic acid [Ley & Yates Organic Process Research & Development 12 120 2008.] Crystallise the acid from H2O, aqueous EtOH, or 30% aqueous AcOH and several times from *C6H6, then dry it in vacuo at 40o overnight. The methyl ester has m 35-39o . [Hope & Riley J Chem Soc 123 2478 1923, Lock Monatsh Chem 90 687 1959, Shorter & Mather J Chem Soc 4744 1961, Beilstein 9 II 228, 9 IV 998.] |
