Delphinidin 3,5-diglucoside chloride reference substance is a primary reference standard with certified absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities).
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 delphinidin 3,5-diglucoside.
