Catalog Number: 5066
Chemical Name: α-Phenyl-N-[4-[(2-thiazolylamino)sulfonyl]phenyl]benzeneacetamide
Biological Activity
Potent and selective inhibitor of human NaV1.3 and NaV1.1 channels (IC50 values are 13 and 23 nM respectively). Exhibits up to 1,000 fold selectivity against other TTX-sensitive or resistant sodium channels (IC50 values are >10 μM for human NaV1.5 and NaV1.8 channels). Interacts with an inhibitory interaction site distinct from those bound by TTX and local anesthetic-like modulators.

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?
