Catalog Number: 2208
Chemical Name: 1-[5-Ethyl-2-hydroxy-4-[[6-methyl-6-(1H-tetrazol-5-yl)heptyl]oxy]phenyl]ethanone
Biological Activity
Selective, competitive antagonist of BLT2 receptors (IC50 values are ~ 1 and > 10 μM at human recombinant BLT2 and BLT1 receptors respectively). Inhibits LTB4-induced contraction of lung parenchyma (pA2 = 7.2), and reduces LTB4-mediated airway obstruction in guinea pigs following i.v. and oral administration.�.

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?
