Catalog Number: 2635
Chemical Name: N-[4-[4-(2,3-Dichlorophenyl)-1-piperazinyl]butyl]-9H-fluorene-2-carboxamide
Biological Activity
Potent and selective dopamine D3 receptor antagonist (Ki values are 1.4, 217, 223, 642, > 5000, > 10000 and > 10000 nM for D3, D2, 5-HT2, α1, D4, D1 and D5 receptors respectively). Potently antagonizes quinpirole-stimulated mitogenesis (IC50 = 6.8 nM). Attenuates cocaine's rewarding effects and inhibits relapse to drug-seeking behavior.

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?
