Usage

Use this template for substances, mixtures, laboratory media, preservation fluids, toxins, and other chemical materials. It is meant to summarize chemistry, physical properties, safety, and documented use without repeating the same fact under several labels.

Field guidance

Choose fields that add distinct information. Do not fill several rows with the same organization, the same use, or the same hazard phrased in different ways.

chemical_class

Broad chemical family or practical category, such as aldehyde-based preservative, cyanide compound, electrolyte-buffered nutrient medium, or oxidizing agent.

compound_type

More specific material type, such as solution, mixture, fixative, medium, salt, gas, or polymer. Do not repeat the chemical class.

composition

Main ingredients or formulation basis. Use this for mixtures and fictional formulations where exact formulae are not known.

formula

Molecular formula for a defined compound. Do not use this for a vague mixture unless the article identifies one principal compound.

function

Primary chemical or biological action, such as tissue fixation, cellular respiration inhibition, pH buffering, or osmotic support.

uses

Documented application or context of use. This should describe where people used the substance, not restate the function.

physical_state

Normal state or form under relevant storage or use conditions, such as liquid, aqueous solution, gas, solid, or crystalline residue.

appearance

Visible description: color, clarity, texture, or deposit. Keep it observational.

hazards

Safety classification or principal danger, such as toxic, corrosive, flammable, biohazard, or lethal poison.

toxicity

Mechanism or severity of toxic effect, if known. Use plain scientific language.

exposure_routes

Relevant exposure pathways, such as inhalation, ingestion, skin contact, injection, or environmental release.

handling

Required handling method, not who had permission to access it.

storage

Storage condition or container type, such as sealed container, refrigerated storage, locked chemical tank, or inert atmosphere.

stability

Notable stability, decomposition, reactivity, or shelf-life information.

developed_by

Person or organization credited with development. If the developer and manufacturer are the same, fill only the more useful row unless the distinction matters.

manufacturer

Entity that produced the material.

associated_facility

Facility strongly tied to production, storage, use, or discovery.

status

Current availability or confirmed final state, such as destroyed, seized, discontinued, active, or unaccounted for.

Avoiding repeated rows

• Do not use both |chemical_class= and |compound_type= for the same wording.
• Do not use |function= to repeat |uses=. Function is what the chemical does; uses are where or why it was applied.
• Do not repeat one organization in |developed_by=, |manufacturer=, and article text unless the distinction is important.
• Do not use access-control details as chemical data. Put staff permissions, control panels, or facility security in the article body.
• Prefer measured or observable properties over vague labels. For example, use aqueous liquid; pale yellow; sharp aldehyde odor instead of only dangerous chemical.

Legacy parameter names

Older articles may use these names. They still work, but new pages should use the clearer names above.
