Template  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  and ), each section is added with this pattern (as the value of a parameter . {{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 . Then a section is defined with "|Section# = {{Chembox " and ends with "}}". Sections cannot 'nest': one must close one section with }} before adding another .  Keep in mind the advice in the main Infobox documentation to use the  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 , since many names use commas within them, and using commas as separators leads to ambiguity.

They should have straight input, such as a correct CAS Registry Number.  Eight base parameters are indexed this way, all identifiers: CASNo, ChEBI, ChEMBL, ChemSpiderID, DrugBank, InChI, KEGG, PubChem, SMILES, UNII, 3DMet, EC_number, RTECS  Then  (like ) is available for free text input.  Same substance, same index When the chembox has multiple substances, you can use the index. Make sure that  and  are about the same substance, and  and  are not. Treat index "0" the same way:  is  is   is  is   is not  is not   Labeling the substances By using a parameter like , you can prefix every #2-input with that same prefix. {{chembox | Name           = [[Linalool]] |Section1        = {{Chembox Identifiers | index_label    =  | index1_label   = (''R'') | index2_label   = (''S'') | index_comment  = (+/-)-linalool | index1_comment = (-)-linalool | index2_comment = (+)-linalool | CASNo          = 78-70-6 | CASNo1         = 126-91-0 | CASNo2         = 126-90-9 | CASNo_Ref      = {{cascite|correct|CAS}} | PubChem        = 6549 | PubChem1       = 443158 | PubChem2       = 67179   }} }}   For specific additions, each parameter has a  option. | CASNo_Comment  =  | CASNo1_Comment =  | CASNo5_Comment =    Use of the  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  in an infobox that follows any identifier means it has not been verified. See WP:CHEMVAL for more details.  Section subtemplates The following section subtemplates are available:  And the automated section, that is visible when 'pagename (data page)' exists:  See these subsections for their parameter options.  The order of these sections in the infobox is set by the section number () only. Not by the typed sequence. This documentation keeps this arbitrary order: | Section1 = {{Chembox Identifiers}} | Section2 = {{Chembox Properties}} | Section3 = {{Chembox Structure}} | Section4 = {{Chembox Thermochemistry}} | Section5 = {{Chembox Explosive}} | Section6 = {{Chembox Pharmacology}} | Section7 = {{Chembox Hazards}} | Section9 = {{Chembox Related}} Sections that are not used can be safely removed, renumbering is not necessary.  Container only  can be used to show a subsection only, for example . When set : The main  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 .  Automatic generation The Wikipedia Drugbox and Chembox Maker can be used to automatically generate chembox templates. For quicker access, this tool can be added to the tools section of Wikipedia's left sidebar via User:Qwerfjkl/scripts/chemboxmaker. The Wikipedia template filling tool by Diberri and Boghog is another option for automatic chembox generation but fills fewer fields.  Adding images  Parameters Image parameters for the first images: {{Chembox <!-- Other chembox parameters can go here --> <!-- Row 1/7 --> | ImageFile      =  | ImageName      =  | ImageSize      =  | ImageAlt       =  | ImageCaption   =  | ImageFile_Ref  =  <!-- Row 2/7 --> | ImageFile1     =  | ImageName1     =  | ImageSize1     =  | ImageAlt1      =  | ImageCaption1  =  | ImageFile1_Ref =  <!-- Row 3/7 --> | ImageFileL1    =  | ImageNameL1    =  | ImageSizeL1    =  | ImageAltL1     =  | ImageCaptionL1 =  | ImageFileL1_Ref=   | ImageFileR1    =  | ImageNameR1    =  | ImageSizeR1    =  | ImageAltR1     =  | ImageCaptionR1 =  | ImageFileR1_Ref=   | ImageCaptionL1R1=  <!-- More chembox parameters can go here, like |Section1=... --> }}  Examples Image parameters for an image (example: File1). All are optional.  {{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 }}  Adding two images:  {{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 | 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 | 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 | 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 + Chembox image ordering  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  ImageFile  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 | 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.

Maintenance Troubleshooting When supplying a parameter with a value, and nothing or the wrong value shows up, check: Is the parameter placed in the correct section? Are the sections properly defined? Sections start with | Section# = {{Chembox sectionname |" and end with "}}". Is there inconsistency in the Section numbering? Available numbers for sections are 1 – 9.
