Application:
2-Methyl-4-Nitrobenzoic Acid (CAS 1975-51-5) is used as a pharmaceutical intermediate in the synthesis of Tolvaptan (CAS 150683-30-0). Tolvaptan is a selective, competitive arginine vasopressin receptor 2 antagonist with an IC50 of 1.28μM for the inhibition of AVP-induced platelet aggregation. Tolvaptan is used to treat hyponatremia (low blood sodium levels) associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). Tolvaptan was approved by the U.S. Food and Drug Administration on May 19, 2009, and is sold by Otsuka Pharmaceutical Co. under the trade name Samsca.
