Catalog Number: 4014
Alternate Names: Alendronate sodium
Chemical Name: P,P'-(4-Amino-1-hydroxybutylidene)bis-phosphonic acid monosodium salt
Biological Activity
Osteoclast-mediated bone resorption inhibitor. Binds and blocks farnesyl diphosphate synthase (FPPS) in the HMG-CoA pathway (IC50 = 460 nM for recombinant human FPPS); causes macrophage apoptosis. Inhibits prenylation and sterol biosynthesis in purified osteoclasts.

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?
