Online database search service

The online database search service through STN, covers all areas of chemistry, such as chemical business information, chemical hazards and biological and medicinal sciences. The STN website has more information on the individual databases.

By carrying out an online search with us members can benefit from: 

• Access to a wide variety of technical and business databases  
• Databases with extensive backfiles updated regularly (some daily) and powerful data mining features
• Indexing systems which can fully encompass concepts while focusing the search
• Experienced chemical information specialists to carry out the work
• Competitive costs - you can set your own cost maximum for any search
• Easy forwarding and receipt of results
• Continuous communication for specification and clarification of search needs  

Members can especially take advantage of our expertise in chemical structure searches.  Chemical substructure searches are conducted in databases such as Chemical Abstracts, Beilstein and Derwent's World Patent Index. This is an invaluable tool for chemists and some of its main applications include:

• Assessing the novelty of a compound 
• Identifying potentially new compounds from a basic structure  
• Focussing on particular structure features 
• Correlating certain chemical or biological activities with structures 
• Avoiding the pitfalls of nomenclature ambiguities 
• Finding CAS registry numbers
