Impurity Standard Issue

I am trying to validate an already existing rel subs method for a new impurity. It is available commercially but leads to 3 peaks upon injection on HPLC-UV. I notice all the CoAs for the standard online the purity is assessed by GC.

What would be the reason in this instance why GC would work better?
