Organic chemistry is concerned with carbon compounds. There may be important information sources on related pages (for example, pricing information and safety sources are under chemistry, general, and many spectra resources are under chemistry, analytical). You may also want to consult related pages such as biochemistry and biophysics, chemistry, physical; and chemistry, polymers.
