Bring the power of IUPAC naming to your desktop!

ACD/Name (Chemist Version) offers a standardized set of features for quick and simple generation of IUPAC names, and structures from names. It is a streamlined version of our popular ACD/Name software.

Characteristic (Functional) Groups

R-3.2.2 Functional modifiers

Many derivatives of principal characteristic groups or functional parent compounds (see R-3.3) may be named by name modifiers which consist of one or more separate words placed after the name of the parent structure. This method is most useful in an indexing environment.

Note: For indexing purposes, this method is used in Beilstein for esters, acyl halides, amides, hydrazides, lactones, lactams and nitrogen derivatives of carbonyl compounds (oximes, hydrazones, etc.). For indexing purposes, this method is also used in Chemical Abstracts index nomenclature for anhydrides, esters, hydrazides, hydrazones and oximes.

Examples to R-3.2.2


Propanal
Propanal dimethyl acetal

Propanal oxime

Propanal hydrazone

Propionic acid
Propionic acid methyl ester

Propionic acid hydrazide
Note: The use, in this section and elsewhere in this guide, of systematic names, such as propanal and propanoic acid, rather than retained names (see R-9.1), such as propionaldehyde and propionic acid, illustrates that, even though some names are retained, this does not preclude use of the systematic names.
