Assay
Dilute an accurately measured volume of not less than 1 mL of Injection to make a solution containing approximately 0.1 µg of riboflavin per mL. Using this as the Assay Preparation, proceed as directed under Riboflavin Assay 481. Calculate the quantity, in mg, of C17H20N4O6 in each mL of the Injection taken by the formula:
C(A / B)
in which C is the concentration, in mg per mL, of C17H20N4O6 obtained for the Assay Preparation, A is the test specimen dilution volume, in mL, and B is the volume, in mL, of Injection taken.
