Catalog Number: 1391
Chemical Name: 4,4',4'',4'''-[Carbonylbis(imino-5,1,3-benzenetriyl-bis(carbonylimino))]tetrakis-1,3-benzenedisulfonic acid, octasodium salt
Biological Activity
Potent purinergic receptor antagonist that displays high selectivity for P2X1 (IC50 values are 0.28, 0.69, 120, 1820, 47000 and > 300000 nM for rP2X1, rP2X1+5, rP2X2+3, rP2X3, rP2X2 and P2X4 receptors respectively). Provides antithrombotic protection in vivo. Also acts as a Gsα-selective antagonist.

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?
