CHEM 223: Organic Chemistry
Librarian: Josh Wilson
Physical and Chemical Properties
- Aldrich: Advancing Science
(Aldrich Catalog Handbook of Fine Chemicals)
D. H. Hill Reference TP202 .A42
ALSO: Copies held in several Fox building labs
ALSO: On the web at http://www.sigmaaldrich.com/
Chemicals are listed in alphabetical order. Your compound will be
listed in this catalog, because the assignment was designed this way.
Check the Aldrich Catalog very carefully for your compound. The
entry for 2,4-dinitrofluorobenzene is given below.
If available, the Aldrich Catalog also gives references to the
following sources; however, your compound will not necessarily be listed
in all of these sources:
- Beil. - Beilstein
- Merck - Merck Index
- FT-NMR - Aldrich Library of 13C and
1H NMR Spectra
- FT-IR - Aldrich Library of FT-IR Spectra
- RTECS - Registry of Toxic Effects of Chemicial
Substances
- Safety - Sigma-Aldrich Library of Chemical Safety Data
Refer to the legend page near the front of the book for more detailed explanations of each entry.
To find property information not contained in Aldrich,
see other resources listed in your quick reference guide and on this site.
- Merck Index - abbreviated
Merck in Aldrich Catalog
D. H. Hill Reference RS51 .M4
Also available electronically on NCSU
Libraries workstations (in library only, no remote access). On
the workstation Start menu, look in the folder for "Locally Networked
Databases."
[This is a case where the printed version is still a lot more convenient!]
To use the printed volume of Merck Index:
- Consult "Cross Index" to locate compound.
2,4-Dintro-1-fluorobenzene see
4101.
- Entry-numbered section gives the following information:
- CRC Handbook of Chemistry &
Physics
D. H. Hill Reference QD65 .C44
Chemicals are listed by inverted form of name in the table "Physical
Constants of Organic Compounds." For example, the inverted form of
2,4-dinitro-1-fluorobenzene is "Benzene, 2,4,-dinitro-1-fluoro"
(see below). This table may give molecular
weight, boiling point, melting point, density, index of refraction (ND),
and
other data.
- Dictionary of Organic Compounds
D. H. Hill Reference QD246 .D5
Use the CAS Registry Number Index (separate volume of
Dictionary of Organic Compounds) to obtain the entry letter
and number for your compound (in this case, F-0-00446).
- Handbook of Data on Organic Compounds
(CRC)
D. H. Hill Reference QD257.7 .H36
- ChemNetBase
- Available through NCSU Libraries databases.
Includes information from the Combined Chemical Dictionary, The Handbook of Chemistry & Physics,
Polymers: A Property Database, and Properties of Organic Compounds. Search
the appropriate book(s), preferrably by CAS number. Click "submit
search" in the upper left corner after entering searching terms.
- PubChem
Available through the NIH and NLM. An increasingly useful and vital database, supplied freely to the
public. Do NOT use CAS numbers to search here (since NIH is somethine of a competitor to the Chemical Abstracts
Service, they use their own ID system). Try using common names or formulae, but make sure you're
examining the right chemical.
- ChemFinder -
http://chemfinder.camsoft.com/
- The best way to search ChemFinder database for this assignment
is to enter the CAS RN
(Registry Number) in the CAS RN box, leave all the other boxes blank, and
click on the [Submit] button.
- Not all chemicals in the CH223 assignment will be in ChemFinder.
- Click on the word ChemFinder above to connect to the database.
- Below the property information for a compound, ChemFinder will link to
other web sites with chemical information.
- ChemExper -
http://www.chemexper.com/
Another source on the web that you might want to try. ChemExper
contains 60000+ compounds together with their physical properties such as
boiling point, melting point, IR spectrum (5000+), MSDS (12000+),
supplier information, 2D and 3D structures.
