Catalog Number: 4305
Chemical Name: N-(2-Chloro-5-pyrimidinyl)-3,4-difluorobenzamide
Biological Activity
Selective KV7.2/KV7.3 (KCNQ2/3) channel opener (EC50 = 0.69 μM). Exhibits 20-fold selectivity for KV7.2/KV7.3 over KV7.3/KV7.5, with no measurable activity over a panel of cardiac ion channels. Hyperpolarizes resting membrane potential and inhibits spontaneous action potentials in guinea pig detrusor muscle (DSM) isolated cells. Orally active in animal models of epilepsy.

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?
