Echimidine perchlorate reference substance is a primary reference standard with certified absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities).
Please note that the given CAS # refers to the free base as there is no CAS # for the perchlorate salt available.
The counterion is determined quantitatively and treated as an impurity in the calculation of the absolute purity of this reference substance. The assigned absolute purity on the certificate of analysis of this reference standard, therefore, refers to the pure echimidine.
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.
