Can I perform structural similarity searches?

Yes, you can perform similarity searches to find structurally related compounds by providing a query SMILES and specifying a Tanimoto similarity threshold.

Does this skill require any external Python packages?

Yes, to use the full capabilities of this skill, you should have 'pubchempy' and 'requests' installed in your Python environment.

What molecular properties can I retrieve?

You can access a vast range of data including molecular weight, XLogP, TPSA, rotatable bond counts, charge, complexity, and hydrogen bond donor/acceptor counts.

Are there rate limits for PubChem API access?

Yes, PubChem requests are generally limited to 5 per second and 400 per minute. This skill includes best practices for handling these limits and managing requests efficiently.

How does this skill search for chemical compounds?

The skill supports flexible searching by chemical name, Compound ID (CID), SMILES strings, InChI, InChIKey, and molecular formulas using the PubChemPy library.
