Pro Tip

Most databases work in a similar way but look very different. Always start by inputting your compound in the central search bar. In SciFinder, you'll have to double-check that you're in the "Substances" tab. Click on the appropriate heading/record to see additional details.

If you're using the CRC Handbook, look for the Properties of Organic Compounds section. Then, click on the Physical Constants of Organic Compounds link to view the full list for your assigned compound.

If you're using either the Combined Chemical Dictionary or PubChem, simply search with the name of your compound and open its record. On that page just scroll down to view all the physical/constant properties available from that database.

Whichever resource you use, the CAS Registry Number may be labled differently. ALL CAS Registry Numbers are a numeric identifier that can contain up to 10 digits divided by hyphens into three parts. Some databases will state it as the RN, others will spell it out entirely, and then others will just label as CAS. Either way, always look for a numeric number split into 3 sections.

For structure (a graphic representation of the molecular structure) look for an image.

Below is the National Fire Protection Association warning label for hazards. This is used in the U.S. only. This diamond serves as quick visual information for first responders. As you read the diamond, remember that a larger number translates into a greater danger. 

Both of these are commercial websites, which means you could purchase chemical solutions like you were on the job. 

Record the unit size (e.g., mL or L) and the price in dollars.

For A9 and A10, a good place to start is the Spectral DB for Organic Compounds (SDBS). When you arrive on the homepage, make sure to enter your compound name. Look at the results columns before you start clicking. Try to find the IR and NMR spectra for you compound. If available, there will be a Y in that column. Click on that Y to show the full spectra.

• Remember! Make sure to switch resources when you can't find certain answers. Don't grab a property detail for a different compound than the specific one you were assigned. If you're having trouble, please let the librarian know. We'll guide to a source that can provide the necessary info.

If you need another source, NIST Chemistry WebBook is a good choice. Start by performing a name search, then select your assigned compound to open its record. Scroll down until you see the sections labeled: Information on this page and Other data available.
