This page is a redirect. The following categories are used to track and monitor this redirect:

From a chemical formula: This is a redirect from a chemical/molecular formula to its systematic (technical) or trivial name.

When appropriate, protection levels are automatically sensed, described and categorized.

Usage

This redirect category (rcat) template populates both Category:Redirects from chemical formulas and Category:Printworthy redirects by default. In 2003, efforts were begun to support the Wikimedia Foundation's goal of increasing access and availability of Wikipedia articles in printed versions. Redirects from chemical formulas are suitable for a printed version. In other words they are printworthy.

Please do not alter the printworthy settings of this rcat without first notifying the Version 1.0 Editorial Team, who are responsible for any and all materials, including redirects, that go into a printed version of Wikipedia.

Place this rcat on a redirect page (not a talk-page redirect) in the following manner:

#REDIRECT [[(target article title)]]

((Rcat shell|
((R from chemical formula))
((R printworthy))
))

Template ((Rcat shell)) is an alias for the Redirect category shell template, which may be used to add as many appropriate rcats as needed, usually from one to seven, along with their parameters, to a redirect. For more information see the documentation on its template page. This rcat may also tag a redirect individually:

#REDIRECT [[(target article title)]]

((R from chemical formula))

This is in accord with instructions found at Wikipedia:REDCAT.

Use this rcat to tag any mainspace redirect that is a chemical formula and targets either the scientific (technical) name or the common name of the chemical compound.
