"So, just what is the structure for draconic acid?"

Save yourself valuable time by looking up a structure by its trivial name in the handy ACD/Dictionary. Information at your fingertips!

ACD/Dictionary contains more than 158 000 systematic and non-systematic names, registry numbers, and abbreviations along with the corresponding molecular structures of the most frequently used chemicals and biomolecules classified by more than 200 therapeutic categories. Additionally, names and structures of inhibitors for more than 500 enzymes are also included.

Dictionary is bundled with all commercial copies of ChemSketch. With Structure mode selected, the Dictionary button is found in the upper right-hand quadrant of the ChemSketch interface.

Note: The freeware version of ChemSketch does not contain Dictionary.

INN (International Nonproprietary Names), USAN (United States Adopted Names), BAN (British Approved Names), JAN (Japanese Accepted Names) and other marks have been added to the corresponding names to indicate the naming preferences of international organizations.

In ACD/Dictionary you can:
