Substanznamen sind ungeignet
• unterschiedliche Schreibweisen (IUPAC, etc…)
• Trivialnamen (z.B. Salzsäure, Natronlauge, Zyankali)
• Synonyme und ID (z.B. AHNO 5555, CAS 100-52-7)
• Nomenklatur komplexer Strukturen problematisch
• ACD/IUPAC Name ACD/Name-to-Structure
• BioRad IUPAC NameIt und DrawIt
► Datenbankrecherchen fehleranfällig
► Zu umständlich
