CodenameExplanation
 t
converts to traditional name. This option generates a common name if one is known for the structure. Otherwise, it generates a systematic name, but sometimes uses some traditionally accepted rules instead of the strict application of the IUPAC rules, when that generates a simpler name.
 i
converts to IUPAC name (default).
 common
generates the most popular common name of a structure. (It fails if none is known.)
 common,all
generates all common names of a structure.
 source
outputs the name present in the source data (no generation).
 CAS#
Fetches the CAS Registry Number® of the structure. This option uses a public internet webservice, so do not use it with confidential structures. ChemAxon assumes no liability whatsoever. Read the notice about CAS Registry Numbers® for more information. In case the structure corresponds to several CAS Registry Numbers, they are all returned, separated by commas.
 singleCAS#
Fetches the CAS Registry Number® of the structure. This option uses a public internet webservice, so do not use it with confidential structures. ChemAxon assumes no liability whatsoever. Read the notice about CAS Registry Numbers® for more information. In case the structure corresponds to several CAS Registry Numbers, the lowest one (historically assigned earlier) is returned.
 ascii
Use only ASCII characters to encode the name.
 timeout=<N>
Use at most N seconds for the name to be computed. The default timeout is currently 20 seconds (which should normally only be reached exceptionally, for very large structures). A value of 0 means no timeout.
