Chemical Data & Sources

Chemical tooltips render normalized fields from MyChem.info records.

Area	Example fields
Identity	name, identifiers, match context
Structure	formula, molecular weight, SMILES, InChIKey
Descriptions	summaries and source text
Synonyms	common names and aliases
Classes	chemical categories and classifications
Pharmacology	targets, indications, mechanisms, bioactivity
Regulatory	approval status, products, designations
Safety	adverse effects and safety annotations

Chemical summary text may include simple inline formatting from source records, such as ChEBI emphasis tags. Bio Tooltips renders a small allowlist of inline tags (em, i, strong, b, sub, and sup) and escapes other markup or attributes.

Source Comparison

MyChem.info aggregates chemical records from multiple data sources. Bio Tooltips presents a curated tooltip view instead of exposing every raw field by default.

Data source	Typical use
PubChem	structures, names, formulae, CIDs
ChEMBL	bioactivity, targets, molecule IDs
ChEBI	ontology identifiers and classifications
DrugBank	drug identifiers, pharmacology, product context
UNII	substance identifiers

Use sourcePaths: true while developing chemical tooltip sections to inspect which MyChem paths contributed rendered fields. See Chemical Configuration & Examples for setup.

For exact type details, see the generated MyChem types.
