Template {{Chembox}} is an infobox for chemicals. It has a large number of options to add relevant data and images. The infobox is organized in sections like "identifiers" and "hazards".
Usage
The Chembox has a modular design. After the general information like the chemical name and images, it can be built from multiple sections, each covering a group of information (like "pharmacology"). Depending on the compound, sections can be added or left out, and within a section parameters can be added or omitted (left blank).
The sections and their parameters are listed below.
Within the general chembox template (with its own parameters like |ImageFile= and |IUPACName=), each section is added with this pattern (as the value of a parameter |Sectionx=.
{{Chembox| ImageFile =| IUPACName =<!-- more general Chembox parameters here -->| Section1 ={{Chembox Identifiers| CASNo =| PubChem =<!-- more Identifier parameters here -->}}}}
In this format, spaces and new lines have no meaning and can be used freely to separate sections (though within a data value, a space has a meaning, except generally leading and trailing spaces).
Each section has its own number in |Section#=. Then a section is defined with "|Section# = {{Chembox " and ends with "}}". Sections cannot 'nest': one must close one section with }} before adding another |Section#= {{Chembox ....
Keep in mind the advice in the main Infobox documentation to use the {{Unbulleted list}} template to present multiple values for a parameter so as to ensure that the values are each started on a new line and tagged appropriately in the underlying markup. This is particularly important with parameters like |OtherNames=, since many names use commas within them, and using commas as separators leads to ambiguity. For example:
.
Reference, use <ref>...</ref> and add <references /> to the page
Title (default: article name)
IUPAC name
The preferred name
The systematic name(s)
Any other name(s)
.

A non-default data page name (default, eg for ammonia: "[[Ammonia (data page)]]")

Alt text for picture (example: Fine dry white powder)
Image link title
Set this to "skin-invert" for black-on-transparent chemical diagrams

Full form
To use, simply copy and paste the left column into the document, and press save to get an empty Chembox:
Then |_Other= (like |CASNoOther=) is available for free text input.
Same substance, same index
When the chembox has multiple substances, you can use the index. Make sure that |CASNo3= and |SMILES3= are about the same substance, and |CASNo3= and |SMILES2= are not. Treat index "0" the same way:
|CASNo= is |InChI= is |SMILES=
|CASNo1= is |InChI1= is |SMILES1=
|CASNo= is not|InChI1= is not|SMILES4=
Labeling the substances
By using a parameter like |index2_label=, you can prefix every #2-input with that same prefix.
Use of the |CASNo_Ref={{cascite|correct|CAS}} parameter with argument places a small, green check mark, , after the CAS No., which indicates that an editor has confirmed that the CAS No. is correct. A red x in an infobox that follows any identifier means it has not been verified. See WP:CHEMVAL for more details.
See these subsections for their parameter options.
The order of these sections in the infobox is set by the section number (|Section#=) only. Not by the typed sequence. This documentation keeps this arbitrary order:
Sections that are not used can be safely removed, renumbering is not necessary.
Container only
{{Chembox}} can be used to show a subsection only, for example Section3={{Chembox Hazards|...}}. When set |container_only=yes: The main {{Chembox}} is not tracked at all (image checks, bot validation categories, etc.), and the Footer (with STP notice) is suppressed. Example: Bromine#Biological role and toxicity. The article will be listed in Category:Chembox container only (48).
Image parameters for an image (example: File1). All are optional.
Chembox
A caption shows here
Chemical compound
{{Chembox| ImageFile1 = Furfural.svg
| ImageAlt1 = Skeleton formula of a ring of four carbons and one oxygen, with a carbon-oxygen attached to a carbon next to an oxygen
| ImageName1 =| ImageCaption1 = A caption shows here
| ImageSize1 =| ImageFile1_Ref = ref
| ImageClass1 = skin-invert <!-- Use this for black-on-transparent chemical diagrams -->}}
Adding two images:
Chembox
Chemical compound
{{Chembox| ImageFile = Furfural.svg
| ImageAlt = Skeleton formula of a ring of four carbons and one oxygen, with a carbon-oxygen attached to a carbon next to an oxygen
| ImageClass = skin-invert
| ImageFile1 = Furfural-3D-vdW.png
| ImageAlt1 = 3D filled-sphere model of the same molecule
}}
This gives two images, each image on his own row (note, ImageFile is the first image, ImageFile1 is the second).
Adding two images, side by side (L1 and R1):
Chembox
Chemical compound
{{Chembox| ImageFileL1 = Furfural.svg
| ImageAltL1 = Skeleton formula of a ring of four carbons and one oxygen, with a carbon-oxygen attached to a carbon next to an oxygen
| ImageClassL1 = skin-invert
| ImageFileR1 = Furfural-3D-vdW.png
| ImageAltR1 = 3D filled-sphere model of the same molecule
}}
This gives one row with two images. Note that ImageFile is now not supplied.
Multiple images

ImageFileL2
ImageFileR2

ImageFile3
row 7
ImageFileL3
ImageFileR3
This gives the possibility to play a bit with which image is first (rows with empty parameters are not displayed). Example:
{{Chembox| ImageFileL1 = Furfural.svg
| ImageAltL1 = Skeleton formula of a ring of four carbons and one oxygen, with a carbon-oxygen attached to a carbon next to an oxygen
| ImageFileR1 = Furfural-3D-vdW.png
| ImageSizeR1 =| ImageAltR1 = 3D filled-sphere model of the same molecule
| ImageClassR1 = skin-invert
| ImageFile2 = Water droplet blue bg05.jpg
| ImageAlt2 = Water droplet erupting from the center of a concentric ring of ripples, evidently in response to a drop landing in the water just before
| IUPACName = example
}}
This gives one row with two images, and one row with one image.
