Properties & Identification
- Combined Chemical Dictionary
-
Not a dictionary at all, the CCD is a database combining several large compound catalogs, including the venerable Dictionary of Organic Compounds, the Dictionary of Inorganic Compounds, the Dictionary of Organometallic Compounds, the Dictionary of Drugs, the Dictionary of Carbohydrates, and the Dictionary of Natural Products . The database contains over 500,000 compounds and derivatives, and is updated occasionally. Entries contain physical data, structure, names and synonyms, CAS Registry Number, and references to relevant literature for synthesis, properties and spectra.

Handbook Table
CRC Handbook Online 
-
- The CRC is probably the best known reference book in chemistry. Each edition of the CRC contains a table of physical constants for organic compounds, listing molecular weight, physical form, boiling point, melting point, density, nD, solubility, and (in older editions) a Beilstein reference. Consult the table's own indexes by formula, synonym, and CAS registry number. CRC's nomenclature and table arrangement change over time, but a substance is usually found under the common systematic name. Prefer more recent editions.
- Dean's handbook of organic chemistry.
- (2nd ed., McGraw-Hill, 2004)
QD 257.7 G65 2004 Reference
- Sections on properties of organic, inorganic, and organometallic compounds, atoms, radicals, and bonds, thermophysical properties, spectroscopy, electrolytes, equilibrium, etc. in a CRC-like format.
- Handbook of tables for organic compound identification.
- (3rd ed., CRC, 1967)
QD 271.4 R28 1967 Reference
- Tables of melting and boiling points of organic derivatives, organized by functional group, then by solid or liquid, then by increasing melting point. Name index.
- Lange's handbook of chemistry.
- (16th ed., McGraw-Hill, 2005)
Handbook Table
- Complementary and similar to the CRC, Lange's provides extensive data tables on organic compound properties.
- Merck index.
- (15th ed., RSC, 2013)
Handbook Table
- Descriptions of over 10,000 chemicals, drugs, and biological substances. Entries (monographs) include name, synonyms and trademarks, formula, molecular weight, structure, some physical data, and remarks on nature, occurrence and uses. The text of the Merck entry often includes one or more literature or patent references for preparation methods. Indexed by synonym, CAS registry number, therapeutic category and biological activity, and formula. Indexes refer to entry numbers, not page numbers.

Handbook of data on organic compounds. (3rd ed., CRC, 1994)
- QD 257.7 H36 1994 Reference
- This data collection gives names, synonyms, structures, formulas (line and molecular), physical constants, solubilities, spectral data (IR, Raman, NMR, UV, MS), as well as CAS registry numbers and Beilstein references for about 29,000 compounds frequently found in the lab, chemical plants, and the environment. It does not contain literature references or preparation information.
The POC/HODOC grew out of efforts to build a database of chemical properties in conjunction with the CRC Handbook of Chemistry and Physics, and is still associated with the CRC's main table of organic compound properties. The original spectral data in the HODOC were derived from the Atlas of Spectral Data and Physical Constants for Organic Compounds (2nd ed., 1975) and augmented by other sources including the NIST/EPA mass spectra libraries.
- Reaxys
- Reaxys (Beilstein) is by far the largest collection of property data for organic compounds. The printed Handbook is rarely consulted anymore, but previous generations of organic chemists cut their teeth on it.

Handbook Table
-
The Sigma-Aldrich chemical catalog lists thousands of chemical products, reagents, and starting materials. It's particularly useful as a starting point because entries include molecular and structural formulas, basic physical data, and cross-references to Beilstein, Merck Index, Aldrich's spectra and safety collections, and Fieser's Reagents for Organic Synthesis.
