Catalog Number: 1997
Chemical Name: 8-Azido-5,6-dihydro-5-methyl-6-oxo-4H-imidazo[1,5-a][1,4]benzodiazepine-3-carboxylic acid ethyl ester
Biological Activity
High affinity benzodiazepine ligand. Ki values are 3.1 and 5.3 nM for diazepam-insensitive (DI) and diazepam-sensitive (DS) benzodiazepine receptors respectively. Acts as partial inverse agonist at recombinant DS α1-, α2-, α3- and α5-GABAA receptors. Displays partial agonism at DI α4- and α6-GABAA receptors. Antagonizes several behavioral and neurochemical effects of ethanol. Proconvulsant and anxiogenic.

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?
