• Starting your search from a text explore• Obtain all the substances indexed in the

reference list– Answer set must be <1000 references– Refine with structure fragments or calculated

properties• Obtain the older cited references or

forward citing references– Answer set must be <500 references

Citation searching• The CAplus database includes citations from

journal and patent references– Only from 1998-present

• 1997 is in progress– From roman script sources– Over 100 million citations

• Older references can be searched as citing references– Results limited to 1998-present

Analysis of those who referenced paper

Better substance searching• Pharmaceutical compounds are seldom

simple neutral compounds• Beware that salts and mixtures may have

their own CAS Registry number• Better to search known compound as an

exact structure that as a name– Includes different stereoisomers, salts and

mixtures• Can copy/paste a CAS Registry to import

the structure

Styrene-Isoprene polymers

With additional components: 573

Not possible to limit the maximum number of components

Without addl. components: 22

May include some oligomers and radio-labeled compounds

Searching by MF• For addition polymers and most condensation

polymers put the molecular formula of the monomers, separated by dots, within brackets and close with an “X”– (C8H8)x for styrene homopolymer– (C8H8 . C5H8)x for styrene-isoprene polymers

• For structural repeating units of symmetric condensation polymers put the formula of the repeating unit within brackets and close with an “N”– (C14H12O4)n for polybutylene terephthalate– (C2H4O)nCH4O for -methyl--hydroxy PE

Results for (C8H8 . C5H8)x

Coordination CompoundsMolecular Weight

Easily search coordinationcompounds with either a molecular weight or a structure.

Behind the Research Topic Explore feature

• Takes natural language query and search concepts in CAplus and Medline• Concepts are identified using the natural

adjectives and filler words• Concepts are checked for chemical names

– Searched both as name and as CAS RN• Various combinations of terms as candidates

– Exact phrase for a simple question– Terms closely associated in the text (same sentence)– Terms anywhere in the text (same document)

How to add synonyms

• SciFinder includes many different word spellings, abbreviations and many synonyms– Not comprehensive ; please consult your

answers for terms not highlighted in blue• Use brackets to indicate a synonym to a

particular concept– E.g., drug analysis (pharmaceutical analysis)– Could use “OR” in simple cases

More Research Topic features

• Can use a CAS Registry Number in a natural phrase

• Can use words to exclude a concept– Refine by research topic can even start with a

NOT operator• Use quotes to find words as entered• Use WITH when “anding” a list• May use AND when searching• There are limits to the complexity of your

search statement
