To establish the working range of your product/impurity of
interest with respect to the specification mentioned. Also
it is demonstreting that by doing plot for repsonse V/s
concentration linear relation must be seen. It also
justifies that my response is directly proportional to the
concentration of the analyte present.

we are proving the concentration of sample is directly
proportion to area response, why we have to do this means
during stability studies some time we will get above and
below the specification, here linearity is proving your
method is giving linear
