Catalog Number: 1041
Chemical Name: 1-Ethyl-2-benzimidazolinone
Biological Activity
Activator of epithelial KCa channels, stimulates a large and sustained trans-epithelial Cl- secretory response across T84 monolayers. Induces hyperpolarization to the same magnitude as ACh in aortic value endothelial cells. Promotes embryonic stem cell (ESC) differentiation into cardiomyocytes.

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?
