New Substructure/Structure Search
Alfa Aesar, a Johnson Matthey Company, has added a molecular structure and substructure search capability, as well as a search by MDL® number option, to its website at www.alfa.com.
The new structure search function allows Alfa Aesar customers to search for families of building blocks and intermediates through the use of a molecular drawing tool. The user can draw a molecule and search either by substructure, where any instance of the drawn molecule as a complete structure or as a substructure is returned as a search result, or by exact structure where only exact matches are returned. The drawing tool provided is the well-known JME Editor developed by Peter Ertl of Novartis.
To view and test the new structure search, please go to http://www.alfa.com/alf/structure.html.
The MDL® number search allows for searches by MDL® numbers, which are originate from the popular Available Chemicals Directory.
