Organic compound names

This text proposal box:

Trivial names (non-systematic, or "common" names) are favored for use in titles of articles for organic compounds instead of systematic names. Trivial names are usually different from the preferred name following IUPAC nomenclature. For compounds lacking trivial names, as is often the case for complex structures, substitutive nomenclature or other systematic names may be used. The general rule is to use the name most commonly used to refer to the compound, as evidenced by use in reliable sources (in line with WP:COMMONNAME).

Classes of compounds may have more specific guidance on naming, such as the use of international nonproprietary names for pharmaceutical compounds (see below).

Examples of use of trivial names and not systematic names include:

acetic acid	not	ethanoic acid
toluene	not	methylbenzene
lysine	not	2,6-diaminohexanoic acid
1-pentanol	not	pentan-1-ol
benzaldehyde	not	benzenecarbaldehyde
diethyl ether	not	ethoxyethane
benzophenone	not	diphenylmethanone

Systematic and other accepted names for the compound not used as the article title should instead be redirects tagged with the {{R from alternative name}} template and listed in the chembox as other names, with especially significant alternative names mentioned in the lede in bold font.
