Dear All,

I would like to know that, during Calculation of Stock solution Preparation, If 'dried base' and 'As Such' both % Assay (From COA)of reference drug available then, which % assay we consider for calculation of stock solution?

If any reference available regarding that please let me know.

Hi Vishal,

Purity of any compound is the Potency calculated on as is basis. Hence when calculating the concentration of Stock solution one should consider the potency on as is basis only. If not given it can be derived from potency reported on dried or anhydrous basis.

Regards

Chirag

Most scientists today are devoid of ideas, full of fear, intent on
producing some paltry result so that they can add to the flood
of inane papers that now constitutes “scientific progress”
in many areas.    Paul Feyerabend
