Catalog Number: 3250
Chemical Name: 3-(2,5-Difluorophenyl)-7-(1,1-dimethylethyl)-6-[(1-methyl-1H-1,2,4-triazol-5-yl)methoxy]-1,2,4-triazolo[4,3-b]pyridazine
Biological Activity
Subtype-selective GABAA receptor partial agonist. Selectively binds to α1, α2, α3 and α5 subunits (Ki values are 0.79, 0.67, 0.67 and 2.25 nM respectively) but displays no efficacy at α1 (α1-sparing). Exhibits non-sedative anxiolytic, antinociceptive and anti-inflammatory activity in vivo.

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?
