Derwent Chemistry Resource (File 355) Enhances the Chemical and Patent Collections

Derwent Chemistry Resource (File 355) lets you find specific chemical compounds within Derwent World Patents Index (WPI) records. Unique numbers identify specific chemical compounds and form the link between Derwent Chemistry Resource and the corresponding bibliographic indexing in Derwent WPI.

You can extract relevant chemical content from more than one million patents dating back to 1981 in Derwent World Patents Index and search by text fields including:

• Systematic name
• Substance descriptor
• Preferred name
• Molecular formula
• Synonym
• Molecular weight

For example, using the sophisticated indexing, you can find information on polymers, rubber and plastics or target patent information specific to pharmaceuticals, agrochemicals and general chemicals.

How It Works

Using DialogLink 5, BEGIN in Derwent Chemistry Resource (File 355) and enter the chemical name, restricted to the suffix /NA.

?s azoxystrobin/na
       S1 1 AZOXYSTROBIN/NA

TYPE out the record and click "Links," which takes you to Derwent World Patents Index. You can then pick up the 108 patent records that include this chemical structure.
