Catalog Number: 3733
Chemical Name: 5-(5,5-Dimethyl-2-oxido-1,3,2-dioxaphosphorinan-2-yl)-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3-pyridinecarboxylic acid 2-[phenyl(phenylmethyl)amino]ethyl ester hydrochloride monoethanolate
Biological Activity
Selective blocker of L-type and T-type Ca2+ channels. Displays minimal inhibition of N- and P/Q-type channels and no inhibition of R-type channels. R(-) and S(+)-enantiomers display different channel selectivity; S(+)-Efonidipine blocks L-type and T-type channels whereas R(-)-Efonidipine displays selectivity for T-type channels. Exhibits antihypertensive activity.

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?
