This page presents several chemical infoboxes to present chemical compound data in a standardised form. They are to be used on all chemical articles, and as such are actively being used in the WikiProject Chemicals.
These tables are constructed by experts in the field of chemical sciences, as well as amateurs and may have been edited by less-knowledgeable passers-by or vandals. Although these tables are well designed, and useful to present the relevant chemical data, the accuracy of information they contain cannot be guaranteed. This also applies to the information in the Hazards section, which is provided for reference value only. When handling chemicals, always take the proper precautions as defined also by reliable sources of information, particularly safety data sheets (SDSs) supplied by the manufacturer and/or relevant government agency. Also see Wikipedia:General disclaimer.
All data as presented in these tables are for materials in their standard state, which is defined to be 25 °C and 100 kPa, unless other conditions are explicitly indicated.
These templates are for creating new infoboxes in wikipages which have no (current) infobox yet. The following steps indicate how to do this.
See What links here in the toolbox on this wikipage, and the Chemicals WikiProject worklist to find wikipages as examples of use.
Use H-phrases and P-phrases templates to provide popup explanations of their meanings. R and S phrases are long obsolete.
If using the full Chembox, a supplementary page should be created as soon as time allows. This is most simply done by clicking on the red link in the table Supplementary data page, then type {{subst:Chembox supplement}}. Save the page, then edit to enter the information.
A bot tracks these infoboxes to validate certain data (like CAS RN), and to track changes to usually stable values (like melting point).
See WP:CHEMVAL.
