Catalog Number: 5181
Alternate Names: OPC-41061
Chemical Name: N-[4-[(7-Chloro-2,3,4,5-tetrahydro-5-hydroxy-1H-1-benzazepin-1-yl)carbonyl]-3-methylphenyl]-2-methylbenzamide
Biological Activity
Potent and selective competitive vasopressin V2 receptor antagonist (Ki values are 0.06 and 12.3 nM for V2 and V1a receptors respectively). Decreases urine osmolality and increases serum sodium concentrations. Delays the onset of end-stage renal disease in a mouse model of polycystic kidney disease. Exhibits myocardial and renal protective effects in hypertensive heart failure rats. Orally active.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
