Why search for chemical compound information?
•
Searches pertaining to research
– Is it a known compound? – Is it commercially available? – How is it synthesized? – What type of activity does it have? – Does it have toxic effects? – Is it on a regulatory list (such as TSCA)? • • •
Patentability searches Freedom to Operate searches Validity/invalidity searches

Comprehensive chemical information retrieval includes diverse search methods Method
Pros
Considerations
Structure searches – exemplified compounds
- Precise - Search for one compound or for many (broad structure query)
Search the exemplified compound databases which are structure searchable
Structure searches – Markush structures
- Precise/broad way to search - Need appropriate match level settings
Search Markush structure searchable databases
Reaction searches
Precise
Search a reaction searchable database
Chemical name searches
Can retrieve records not indexed by structure or from databases without structure indexing
- Multiple chemical names usually exist - Use a system which supports complex term searching - Can retrieve false drops – not that specific compound - Can supplement structure searches
Name searches (trade names, lab codes, etc.)
Can retrieve records not indexed by structure or from databases without structure indexing
- Search using the various permutations of the lab code - Can supplement structure searches

Patent search example: Flexible electronic devices Graphene is touted as flexible "wonder material” and could be used to produce a flexible mobile phone that would fold like paper1. Its potential use in flexible solar panels is also being explored2. 1http://portal.acs.org/portal/PublicWebSite/education/resources/highschool/chemmatters/archive/CNBP_030982 2http://bits.blogs.nytimes.com/2012/10/12/graphene-could-usher-flexible-ultra-slim-gadgets/

What is graphene?
Source: http://graphene.nus.edu.sg/content/graphene
•
Graphene is a one-atom-thick planar sheet of carbon atoms arranged in a honeycomb crystal lattice
•
Graphite (pencil lead) is composed of sheets of graphene
•
It is the thinnest and strongest possible material
•
It is the best conductor of electricity
• •
It has high opacity (transparent) Other graphitic materials are carbon nanotubes and fullerenes
