File Description [top]

Beilstein Database - Facts is a very comprehensive structure and factual database in organic chemistry. It includes structures and properties for about 9 million heterocyclic, acyclic and isocyclic compounds covered in the chemical literature published from 1771 onwards. From 2000 onward, biomolecules, mixtures and polymers are also included.

Companion files to File 390 are Beilstein Database - Reactions, File 391, which includes the preparations and chemical reactions of the substances in File 390 and Beilstein Database - Abstracts, File 393, which includes the literature citations from which the facts and reactions have been extracted.

Subject Coverage [top]

Substances included in Beilstein Database - Facts must contain Carbon and may also contain any of the following elements from the Periodic Table:

• Group I: H, Li, Na, K, Rb, CS
• Group II: Mg, Ca, Sr, Ba
• Group III: B
• Group IV: C, Si
• Group V: N, P, As
• Group VI: O, S, Se, Te
• Group VII: F, Cl, Br, I

These organic substances may be pure substances with a structural formula or they may be biomolecules, mixtures, or polymers that may be completely or partially described by names or information about their components.

Sources [top]

There are three different data sources for Beilstein Database - Facts:

1. The Beilstein Handbook, Basic Series through Supplement IV, covering journals, books, and patents from 1771 to 1959. Complete evaluated Handbook data with corresponding reference to the original literature.

2. Primary literature, (journals, books, and patents) from 1960 to 1979 that is the basis of the Beilstein Handbook Supplement V that is still being prepared and updated to provide data beyond the basic data (melting point, boiling point, density, refractive index, optical rotatory power, isolation from natural products and chemical derivatives) already in the file. All other data is provided as keywords with the corresponding references to the original literature.

3. Primary literature (176 journals) from 1980 forward. Detailed information for all physical properties, chemical properties and pharmacological and ecological data is abstracted with corresponding references to the original literature.

BASIC INDEX [top]

¹ All words are indexed, including the standard Dialog stop words. Any term in the Basic Index may be limited to a full phrase using /FF, e.g., S PYRIDINE/FF. Any segmented term in the Basic Index may be limited to a full word using /FW, e.g., S PHENOL/FW.

² Fields in section displayed using main display code (includes pertinent references).

³ Searchable in the Basic Index and in the Additional Indexes.

ADDITIONAL INDEXES [top]

⁴ Use /MAIN to restrict a Beilstein Registry Number to the main BN of the record or /OTHER to restrict to other occurrences of the BN in the record.

⁵ All fields in these sections displayable using PP (includes pertinent references).

⁶ For reference or textual data present, search by EXPANDing DPN=field name or RT=field name for comments, e.g., EXPAND RT=LIQUID, RT=EUTECTIC or RT=MELTING DIAGRAM.

PREDEFINED FORMAT OPTIONS [top]

⁷ Record charges for numbered and user defined formats are by the number of chargeable fields actually present. Presence checking is used to determine the number of chargeable fields in a TYPEd or PRINTed record. Any one chargeable field will show a cost estimate using Format 51. Two chargeable fields will be listed as Format 52, etc. Starting with Format 51, no display code is associated with a format number. These formats are only used in estimating costs for the numbered format or display codes used. See HELP RATES 390 online for actual rates and more details.

⁸ Short Data Present includes only each top line in the hierarchy of any data field, i.e, PR, PP, PE.

----------


Because there are no search charges in Beilstein Online, all charges
are related to the data that is viewed, displayed, typed, or printed.
The rates shown for the defined formats 1 - 15 are maximums for each of
these formats.  The actual charge is based on the data fields present
as determined by a presence-checking algorithm.  Therefore, rates for
formats above 15 have been defined for various numbers of and/or
combinations of data fields.  These formats are used only by the
accounting program and are not for searcher use.  Thus it is possible
for the searcher to request, for example, three records to be displayed
format 9, and then, viewing the cost estimate, to see charges for
three different formats, with numbers greater than 15, based on the
actual data present in each of the 3 records.  The displayed records
are still identified with the format number the searcher entered.  User
defined formats are also mapped by the presence-checking algorithm to
the numbered formats above 15.
