Catalog Number: 2519
Chemical Name: 7-[(2,6-Difluorophenyl)methyl]-4,7-dihydro-2-[4-[(2-methyl-1-oxopropyl)amino]phenyl]-3-[[methyl(phenylmethyl)amino]methyl]-4-oxo-thieno[2,3-b]pyridine-5-carboxylic acid 1-methylethyl ester
Biological Activity
Potent, orally active and non-peptide gonadotropin-releasing hormone (GnRH, LHRH) receptor antagonist (IC50 values are 0.2, 4.0 and 60 nM for human, monkey and rat GnRH receptors respectively). Inhibits LH release in vitro (IC50 = 100 nM) and reduces plasma LH concentration in castrated male cynomolgus monkeys.

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?
