Catalog Number: 0991
Chemical Name: 1-[4-Amino-5-chloro-2-(3,5-dimethoxyphenyl)methyloxy]-3-[1-[2-methylsulphonylamino]ethyl]piperidin-4-yl]propan-1-one hydrochloride
Biological Activity
A potent and selective 5-HT4 antagonist, with a pKi of 9.1 at 5-HT4 receptors in guinea pig striatal membranes and greater than 1000-fold selectivity over 5-HT1A, 2C, 3 and D1, D2, M1, M2, AT1, B1 and α1C receptors. The ketone group gives RS 39604 a relatively long half life; it is also orally active and so suitable for in vivo studies.

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?
