The HTML rendering below shows a synthetic Quality data example for Common Technical Document (CTD) Module 3: Quality, section 3.2.S.3 Characterisation, subsection 3.2.S.3.2 Impurities.
This is the same data as in the example files here in xml and in json, presented for easier viewing. Hovering on words below will show the corresponding sections of the underlying data.
