Preferred IUPAC name

139:
Since systematic names often are not human-readable a PIN may be a retained name. Both "PINs" and "retained names" have to be chosen (and established by IUPAC) explicitly, unlike other IUPAC names, which automatically arise from IUPAC nomenclatural rules. Thus, the PIN is sometimes the retained name

that do not contain carbon (inorganic parents). "Preselected names" are used in the nomenclature of organic compounds as the basis for PINs for organic derivatives. They are needed for derivatives of organic compounds that do not contain carbon themselves. A preselected name is not necessarily a PIN

Multiplicative nomenclature is to be preferred over simple substitutive if it can be used. This is the nomenclature with an apostrophe after numbers such as 4'; it allows multiple occurrences of the principal characteristic group or compound class to be treated together. Example:
225:('a', named for the suffix), if it both applies and a heteroatom is found in a chain, is preferred over substitution. If it applies but no heteroatom is found in a chain, it is preferred over multiplicative nomenclature. Example: 3-phospha-2,5,7-trisilaoctane refers to CH 294:
Additive and subtractive operations remain available as with the general case. For example, one keeps changing "ane" into "ene" for double bonds. Additive operations generally have better names derived from the above rules, such as phenyloxirane for

nomenclature. The "preferred IUPAC nomenclature" provides a set of rules for choosing between multiple possibilities in situations where it is important to decide on a unique name. It is intended for use in legal and regulatory situations.
168:(IUPAC) have traditionally concentrated on ensuring that chemical names are unambiguous, that is that a name can only refer to one substance. However, a single substance can have more than one acceptable name, like 290:
Conjunctive nomenclature is available, but substitutive, multiplicative, or skeletal should be preferred. Example: benzene-1,3,5-triacetic acid should instead be named 2,2′,2′′-(benzene-1,3,5-triyl)triacetic
140:(e.g., phenol and acetic acid, instead of benzenol and ethanoic acid), while in other cases, the systematic name was chosen over a very common retained name (e.g., propan-2-one, instead of acetone). 261: 338:
In IUPAC nomenclature, all compounds containing carbon atoms are considered organic compounds. Organic nomenclature only applies to organic compounds containing elements from the Groups

The name for 172:, which may also be correctly named as "methylbenzene" or "phenylmethane". Some alternative names remain available as "retained names" for more general contexts. For example, 322:) has been reduced considerably for preferred IUPAC names, although a larger set of retained names is available for general nomenclature. The traditional names of simple 70:). Rules for the remaining organic and inorganic compounds are still under development. The concept of PINs is defined in the introductory chapter and chapter 5 of the 54:, to which the IUPAC (International Union of Pure and Applied Chemistry) has the definition as compounds which contain at least a single carbon atom but no 165: 103: 619:
