How this service works
PHARMA: physicochemical properties for a compound (PubChem) — formula, MW, SMILES, IUPAC, XLogP, TPSA. ?q=name. Returns JSON.
Output
A JSON object containing the compound's molecular formula, molecular weight, canonical SMILES, IUPAC name, XLogP (lipophilicity coefficient), and TPSA (topological polar surface area), sourced from PubChem.
Example use cases
Example prompt
“Can you look up the physicochemical properties of ibuprofen for me — I need the molecular formula, molecular weight, SMILES, IUPAC name, XLogP, and TPSA?”
Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/compound-propertiesWhen to prefer
Use this endpoint when you need rapid, structured physicochemical property data for a named chemical compound and want PubChem-sourced values for formula, MW, SMILES, IUPAC, XLogP, and TPSA in a single JSON response. Prefer this over raw PubChem API calls when you want a paid, low-latency wrapper with consistent output structure. Best suited for drug discovery, ADMET screening, cheminformatics pipelines, or any workflow that needs lipophilicity or polarity data for a molecule by name.
Side effects
- Compound name not found in PubChem — returns empty or error response
- Ambiguous compound name matching multiple PubChem entries — may return unexpected compound
- Missing or malformed ?q= parameter — returns 400 or error
- PubChem upstream unavailable — returns 502 or timeout
- Non-chemical query string (e.g. brand name not in PubChem) — no results
