Share molecules

1 · Direct link to Studio

The simplest URL. The user clicks and lands directly in the Studio with the molecule loaded in 3D.

https://chemmodel.com/en/lab/?mol=caffeine
https://chemmodel.com/en/lab/?mol=CC(=O)Oc1ccccc1C(=O)O

Accepts names in Spanish or English, or SMILES directly.

2 · Embedded iframe

Shows the 3D viewer directly inside your article or page, without the user leaving.

<iframe
  src="https://chemmodel.com/embed?mol=caffeine&lang=en&h=420"
  width="100%"
  height="420"
  style="border:none;border-radius:10px"
  loading="lazy"
  allow="clipboard-write"

3 · Link to Isomerism Studio

Opens the Isomerism Studio with one or two preloaded molecules for direct comparison.

# One molecule (searches its isomers)
https://chemmodel.com/en/isomeria/?a=caffeine&lang=en

# Two molecules to compare directly
https://chemmodel.com/en/isomeria/?a=caffeine&b=theophylline&lang=en

4 · Public molecule API

REST endpoint returning JSON with all compound properties and ChemModel URLs. Open CORS — use from any origin.

GET https://chemmodel.com/api/molecule?name=caffeine
GET https://chemmodel.com/api/molecule?name=caffeine&lang=en

Example response (simplified):

{
  "cid": 2519,
  "name": "caffeine",
  "iupacName": "1,3,7-trimethylpurine-2,6-dione",
  "formula": "C8H10N4O2",
  "molecularWeight": "194.19",
  "smiles": "Cn1cnc2c1c(=O)n(c(=O)n2C)C",
  "inchiKey": "RYYVLZVUVIJVGH-UHFFFAOYSA-N",
  "xlogp": -0.1,
  "tpsa": 58.4,
  "image2d": "https://pubchem.ncbi.nlm.nih.gov/rest/pug/compound/cid/2519/PNG?...",
  "urlStudio":   "https://chemmodel.com/en/lab/?mol=caffeine",
  "urlIsomeria": "https://chemmodel.com/en/isomeria/?a=caffeine&lang=en",
  "urlEmbed":    "https://chemmodel.com/embed?mol=caffeine&lang=en",
  "urlCompound": "https://chemmodel.com/en/compuesto/caffeine"
}

You can also search by formula or CID:

# By molecular formula

5 · Compound page (SEO)

Each compound has its own indexable page with schema.org, full properties and embedded 3D viewer. Ideal for linking from scientific articles.

https://chemmodel.com/en/compuesto/caffeine
https://chemmodel.com/en/compuesto/fenolftaleina
https://chemmodel.com/en/compuesto/dopamine

Each page includes schema.org ChemicalSubstance, PubChem 2D image, embedded 3D viewer, property table and API access.

6 · PNG image with overlay

From the Studio, load any molecule and use the image button (🖼️) to download a PNG with the name, molecular formula and ChemModel watermark.

The viewer background is dark (#0a0f1e), ideal for dark-themed presentations and articles.
