Reaxys Database Trial through 6/30/09

The UMass Library is pleased to announce a database trial to Reaxys.

Reaxys is a web-based search and retrieval system for chemical compounds, bibliographic data and chemical reactions. Reaxys is based on data from Elsevier’s chemistry databases – CrossFire Beilstein, CrossFire Gmelin and Patent Chemistry Databases.

Offering a wealth of experimentally validated information, Reaxys brings a fresh look to synthetic chemistry with powerful functionality, combined content and relevant information.

Powerful Functionality
Reaxys search, analysis and workflow tools are designed around the needs and common tasks of users, including:
· Synthesis planner to design the optimum synthesis route
· Multi-step reactions to identify precursor reactions underlying synthesis of target compounds
· Additional search capabilities such as the ability to generate structure query from names or phrases
· Search result filters by key properties, synthesis yield, or other ranking criteria
· Results visualization
· Similarity search
· Transformation analysis

Combined Content

The merger of three prestigious databases puts all the relevant data at the user’s fingertips. A search across the Reaxys database delivers a single results set and each record provides details excerpted from multiple patent or journal sources.

Relevant Information
Reaxys contains an extensive repository of experimentally validated data that chemists need including structures, reactions (including multi-step reactions) and physical properties. Now chemists can get relevant data not found elsewhere, drawn from source publications carefully selected for their importance and relevance to synthetic chemists.

To access the database go to the Reaxys link on the database trials page:

Gmelin Database Trial now through 8/30/08

The UMass Amherst Sciences & Engineering Library has arranged for a trial subscription to the Gmelin database now through August 30th.

The Gmelin Database is the sister database to Beilstein, covering inorganic and organometallic compounds from 1772 to date. Based on a German publication, the Gmelin Handbuch der anorganischen Chemie, the database currently comprises over 2.5 million compounds, including glasses, alloys, ceramics, minerals and coordination compounds, 1.9 million reactions and 1.3 million citations.

During this time period we will also have access to the Patent Chemistry Database.

For instructions on how to connect to the database contact Paulina Borrego pborrego@library.umass.edu
