Catalog Number: 3296
Chemical Name: 4-(4-Chlorophenyl)-3-methyl-3-buten-2-one oxime
Biological Activity
Reversible TRPA1 channel blocker (IC50 values are 3.1 and 4.5 μM at human and mouse TRPA1 respectively). Blocks cinnameldehyde-induced but not capsaicin-induced nociception and reverses mechanical hyperalgesia in vivo. Also blocks TRPA1 pore dilation (IC50 = 10.3 μM for the inhibition of Yo-Pro uptake).

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?
