Calculating % analytes in HPLC

When calculating the % of an analyte with HPLC, the raw material used for making the product has a purity of 79%, but the standard used for analysis has a purity of 75%. In the calculation, is there a factor to correct for the purity of the standard, purity of the raw material, or does there need to be a correction at all?
