1H-Pyrazole-3-carbaldehyde

1H-Pyrazole-3-carbaldehyde is the compound identified by CAS Registry Number 3920-50-1 and molecular formula C4H4N2O. Its matched public structure record is PubChem CID 12218383. The verified connectivity is represented by SMILES C1=C(NN=C1)C=O and InChIKey ICFGFAUMBISMLR-UHFFFAOYSA-N. These values provide a consistent name-based and structure-based identity for the catalog record.

The recorded structure contains a pyrazole ring with a carbaldehyde group at position 3. The alternative name 3-formylpyrazole describes the same verified connectivity, while the systematic name preserves the 1H ring designation and the 3-locant. Those details should stay with the record to separate it from another pyrazole carbaldehyde positional form. CAS 3920-50-1, PubChem CID 12218383, the SMILES, and the InChIKey supply matching references for the exact entry. The formula and connectivity also refer to the same neutral compound record.
