| * | DD | ORGANIC COMPOUNDS (Class 532, Subclass 1) {21} |
| 303 | DF | .~ Nitriles (i.e., compounds having cyano bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon) {21} |
| 435 | DF | .~.~ Acyclic (e.g., purification of saturated nitriles, etc.) {9} |
| 440 | DF | .~.~.~ Carbonyl attached indirectly to the cyano group by nonionic bonding (e.g., aldehydes, ketones, etc.) {2} |
| 441 | DF | .~.~.~.~ Oxygen bonded directly to the carbonyl group (e.g., carboxylic acid esters, etc.) {3} |
| 444 |  | .~.~.~.~.~ The oxygen is between the carbonyl and the cyano group (e.g., cyano is in the alcohol portion of a carboxylic acid ester, etc.) |
