FOR NEW COMPOUNDS
Find new compounds important to your
research. Prevent needless duplication of
compound synthesis. Reduce literature
search time from days to minutes. With
the Chemical Substructure Index"T (CSI ).
CSI lets you conduct fast, efficient manual
searches for new chemical .compounds
containing specific substructures or fragments.
It's the only chemical information
retrieval system that gives you this capability
because it describes compounds by
the most effective means available, the
Wiswesser Line Notation (WLN).
Unlike molecular formulas, chemical nomenclature,
or fragmentation codes, WLN
represents each molecular structure with
a unique, unambiguous, alphanumeric
descriptor. So there is no chance of
missing important compounds because
of nomenclature deficiencies.
Chemical Substructure Index is permuted,
too. For each compound, a separate entry
is created for every significant substructure
it contains. So you can easily
employ manual search strategies that are
as sophisticated as those usually reserved
for computer searches.
Find out how CSI can help you keep up
with over 150,000 new compounds each
year, quicker and more effectively than
ever before. Send for our new brochure
