PatSnap Chemical has now integrated a refinement tool based on the properties search.
Every field you see on the properties search can be used as a refinement.
Once you have conducted your search you will see the refining options on the left hand-side of the page.
When clicking into the detailed refinement you will see the below, you can then select what to refine by in the drop down menu and add the specific refinements you require.
This refinement will instantly refine the number of Chemical found or the number of patents.
As you can see from the example above, we have refined by molecular weight and also keyword refinements.
