Category:Multiple chemicals in an infobox that need indexing

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set.

This category lists articles that have a second identifier in {{Infobox drug}}, {{Chembox}}, so there are two or more chemical compounds, while missing an index like |index_label=, |index2_label=. Such labels are useful to specify the different substances (example: linalool).

Maintenance task

Preferably indexes are added, removing the article from this category.

This category is populated by {{Infobox drug}} (talk) (sorted under * and {{Chembox}} (talk).
