Fig. 2From: An open source chemical structure curation pipeline using RDKitExamples of standardisations that have been applied to a set of compounds. The compound structure before and after standardisation is shown. a Fix hypervalent nitro groups, b remove explicit H atoms, c fix covalently drawn alkaline metals connected to O or N to ionic forms, d Standardise sulphoxides to charge separated form, e normalise (straighten) allene bondsBack to article page
