Example: Searching "Aleve" (naproxen) via "Exact (parent only)" retrieves one record. Searching "Aleve" via If the "Flex/Flexplus" retrieves nine records (the parent naproxen record, and seven other salts and mixtures of naproxen). More information about these search features can be found in the Help section of ChemIDplus Advanced at http://chem.sis.nlm.nih.gov/chemidplus/documentation/help/chemidfs2webAd vanced.jsp#_StructureSearch **** NLM-TOX-ENVIRO-HEALTH-L NOTICE **** You are receiving this message as a subscribed member of NLM-TOX-ENVIRO-HEALTH-L, a discussion list available from the National Library of Medicine.
