Catalog Number: 3022
Alternate Names: ET-18-OCH3
Chemical Name: (7R)-4-Hydroxy-7-methoxy-N,N,N-trimethyl-3,5,9-trioxa-4-phosphaheptacosan-1-aminium-4-oxide
Biological Activity
Synthetic lysophospholipid analog that selectively inhibits phosphatidylinositol phospholipase C (IC50= 9.6 μM in fibroblasts and adenocarcinoma cells). Also acts as an agonist at platelet-activating factor (PAF) receptors. Antitumor lipid; selectively induces apoptosis in tumor cells, sparing normal cells.

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?
