Normal the values of x for each of 3 or more dosage ranges to acquire x = M¢, the log-relative potency on the Assay Planning. Establish the amount, in µg, of USP Cyanocobalamin RS corresponding to the cyanocobalamin within the part of material taken for assay because of the equation antilog M = antilog (M¢ + log R), in which R is the quantity of µg of cyanocobalamin which was assumed to become present in Just about every mg (or capsule or tablet) of the material taken for assay.
