These can be installed as follows:

Lookup properties for compound by name or CAS number.

Functions:

get_compounds(identifier[, namespace])

Returns a list of Compound objects for compounds that match the search criteria.
get_compounds(identifier, namespace=<PubChemNamespace.Name: 'name'>)[source]

Returns a list of Compound objects for compounds that match the search criteria.

As more than one compound may be identified the results are returned in a list.

Parameters

  • identifier (Union[str, int, Sequence[Union[str, int]]]) – Identifiers (e.g. name, CID) for the compound to look up. When using the CID namespace data for multiple compounds can be retrieved at once by supplying either a comma-separated string or a list.

  • namespace (Union[PubChemNamespace, str]) – The type of identifier to look up. Valid values are in PubChemNamespace. Default <PubChemNamespace.Name: 'name'>.

Return type

List[Compound]
