How Do I Find Chemical Properties?

How do I find chemical properties?

Do you need to find the molecular weight, melting point, or compound structure for a specific chemical substance? The CRC Handbook of Chemistry and Physics contains the physical constants and diagrams for nearly 11,000 organic compounds. It can be found online or in print at the H.G. Thode Library:

How to search

Begin by going to Section 3 - Physical Constants of Organic Compounds. Substances are presented alphabetically by the primary name of the substance and given a number. You can choose one of the three indexes to find your substance: Synonyms, Molecular Formula (Hill Order: Carbon, Hydrogen, etc.), or CAS Registry Number. When you have selected your index, note the number of the compound. Then locate that number in the first part of Section 3. Find the data you need in the table. The chemical structure of the compound is also illustrated to help you identify the correct compound. The CRC tables rely on abbreviations; a complete list of appears on the introductory portions of the tables.
