The First Edition of the Condensed Chemical Dictionary appeared in 1919 when the chemical industry in the United States was entering a huge expansion program as a result of World War I.
In the Sixteenth Edition, there is significant expansion of both chemical and biochemical terms. The reason for the additions of biochemical terms in the Sixteenth Edition is the emerging fields in biology and biological engineering such as synthetic biology, which highlight the merging of the sciences of chemistry and biology:

-  1471 new definitions, 5,236 revised or updated definitions, a new Chemical Abstract Number index, and an update of all trademarks
-  Significant expansion of both chemical and biochemical terms including the addition of biochemical terms in the emerging fields in biology and biological engineering such as synthetic biology, highlighting the merging of the sciences of chemistry and biology
-  Updates and expands the extensive data on chemicals, trade name products, and chemistry-related definitions
-  Adds entries for notable chemists and Nobel Prize winners, equipment and devices, natural forms and minerals, named reactions, and chemical processes
-  Update on toxicological profiles
