Solvent: Acetonitrile/Water (1:9, v/v) Certified valuesDomoic acid + . 100.9 ± 0.8 μg/g 99.4 ± 0.8 μg/mL (at 24°C) 319 μmoles/L ± (at 22°C) Epidomoic acidPure domoic acid in solution has been found to gradually isomerise, especially to the C5’-diastereomer, epidomoic acid; therefore, a mixture will inevitably result on long-term storage of any standard.The density of the solution is 0.9851 at 24°C.
