How this service works
NIH PubChem compound lookup by name (PUG REST): PubChem CID, title, molecular formula, molecular weight and IUPAC name for the best match. Safety and hazard data are not included. One compound per call.
Output
Returns the best-matching PubChem compound record for the given name, including: PubChem CID (integer identifier), compound title, molecular formula (e.g. C8H10N4O2), molecular weight (numeric, in g/mol), and IUPAC name. Safety and hazard data are not included. One compound per call.
Example use cases
Drug molecular weight verification
“What is the molecular formula and molecular weight of ibuprofen according to PubChem?”
Chemical identifier resolution
“I need the PubChem CID and IUPAC name for acetaminophen — can you look that up for me?”
Biochemistry research assistance
“Can you find the PubChem compound info for dopamine, including its molecular formula and molecular weight?”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/pubchem-chemical-cid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, structured chemical identity data (CID, formula, weight, IUPAC name) for a single named compound from the authoritative NIH PubChem database. Prefer it over general web search when you need machine-readable chemical metadata. Note it does not return safety, hazard, or toxicity data — use a different source for those.
Side effects
- Compound name not found in PubChem — returns no match or empty result
- Ambiguous or misspelled compound name yields an unexpected best-match
- Input name outside allowed character set or length (2–100 chars) triggers validation error
- Network or upstream PubChem PUG REST API unavailability causes timeout or error response
