Catalog Number: 4621
Chemical Name: 1-Ethyl-2-[[3-ethyl-5-(3-methyl-2(3H)-benzothiazolylidene)-4-oxo-2-thiazolidinylidene]methyl]-pyridinium chloride
Biological Activity
Occupies mortalin-2 (mot-2), a member of the Hsp70 family, at its p53 binding site and enables p53 translocation to the nucleus. Selectively cytotoxic; causes growth arrest of cancer cells in culture. Also inhibits telomerase activity and cross-links F-actin.

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?
