Us patent 1950 pharmaceutical compound?

Do you mean a US patent issued in 1950 for a pharmaceutical compound? I can help identify the exact patent if you can share a bit more:

- The compound name (or any identifier), or
- The inventor or company (assignee), or
- The chemical class (e.g., sulfonamides, penicillins, benzodiazepines), or
- Whether you just want to search for any US pharmaceutical patents from 1950.

If you’d like to search yourself, here are good options:

- Google Patents: go to patents.google.com, set the date filter to 1950, and search with keywords like “pharmaceutical,” “drug,” or the compound name. You can also use CPC/IPC codes to narrow (e.g., A61K for medicinal preparations, C07D for heterocyclic compounds).
- USPTO Patents Full-Text (PatFT): use the Advanced Search to limit by publication date in 1950 and by chemical/pharmaceutical keywords or assignee.
- If you know a rough class, you can search by classification (C07D, A61K, etc.) and then filter by year.

If you give me the compound name or any detail, I can try to identify the exact US patent number, title, inventor, assignee, and grant date.
