EC number: 204-464-7
CAS number: 121-32-4
Author give in the publication the value for
Log (IC50-1)= 0.02
with IC50 in mM
So the calculation to deduce IC50 is as
/ [inv Log (0.02)] = 0.955 mM
IC50 = 0.955 * MW with MW = 166.175 g/mol
IC50 = 158.7 mg/L
In a study (Schultz, 1997), the acute
toxicity of Tetrahymena pyriformis was studied under static conditions.
Microorganisms were exposed to at least 5 concentrations of
The 40-hour IC50 was 158.7 mg/L.
Under these conditions, Ethylvanillin is not
considered harmful to microorganisms tested.
