"We have had a relationship with CAS for a long time, hence when we were
required to select an enterprise-wide research platform for our R&D teams,
SciFinder was the clear choice, given its reliable, high-quality content and
advanced reaction planning tools. Our scientists now have on-demand access to
the largest collection of small molecules and related information, including
references to millions of peer-reviewed research papers and patents.
SciFinder gives our researchers the insight they need to produce the flagship
laboratory data for which we are known," said Dr. Sourav Basu, Associate
Vice-President of TCG Lifesciences.

SciFinder, the world's leading research and discovery tool, will offer
TCG Lifesciences teams a variety of powerful research and analysis options,
including Markush searching for retrieving additional patents for substances
that are claimed in generic terms, and the recently-announced SciPlanner(TM),
an interactive reaction planning workspace especially valuable for
pharmaceutical and biotechnology research.

SciFinder's comprehensive and current content, sophisticated analysis and
collaboration capabilities, and demonstrated results inside the lab and out
have made it the preferred source of chemical information for scientists
around the globe. Its streamlined navigation and intuitive interface
integrated with CAS' trusted content gives researchers confidence in the
quality of their work.

"CAS is committed to providing the most complete collection of reliable
chemical information needed by chemists and other researchers to drive
innovation," said Robert J. Massie, president of CAS. "We look forward to
supporting TCG Lifesciences' work in the arena of drug discovery and
