Catalog Number: 1543
Chemical Name: (S)-α-Amino-2,3,4,5,6,7-hexahydro-2,4-dioxo-1H-cyclopentapyrimidine-1-propanoic acid
Biological Activity
Novel subtype-selective and weakly desensitizing AMPA receptor partial agonist (Ki values are 44, 109, 223, 1890 and 2090 nM at GluR5, GluR1, GluR2, GluR3 and GluR4 receptors respectively).

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?
