Epiprogoitrin potassium salt reference substance is a primary reference standard with certified absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities).
This reference substance has been prepacked and is available in 10 mg portions only. Therefore, the discount scheme for larger units is not applicable to this reference standard. The counterion is determined quantitatively and treated as an impurity in the calculation of the absolute purity. The assigned absolute purity on the certificate of analysis, therefore, refers to the pure epiprogoitrin.
