2-Hydrazinylpyridine hydrochloride

2-Hydrazinylpyridine hydrochloride is the product identity associated with CAS 51169-05-2 and molecular formula C5H8ClN3. The Rlavie record and PubChem CID 521315 return the same molecular formula, SMILES C1=CC=NC(=C1)NN.Cl, and InChIKey ZDCGBGBQRTYDFC-UHFFFAOYSA-N. This agreement provides a precise, machine-readable identity for the listed hydrochloride record and anchors the page to a publicly traceable compound entry.

The PubChem structure represents a pyridine ring bearing a hydrazinyl group together with the hydrochloride component recorded for this entry. In the SMILES, the dot separates the organic fragment from chloride, while the molecular formula counts atoms across the complete record. Reading the CAS number, CID, formula, SMILES, and InChIKey together helps distinguish this specific salt entry from a free-base record or from compounds with related names.

For identity review, reference the complete name 2-Hydrazinylpyridine hydrochloride and CAS 51169-05-2 rather than relying on a shortened label alone. PubChem CID 521315 supplies the matching public structure record, and the InChIKey provides a compact identifier for database comparison. When requesting product information, include these identifiers so the intended record can be checked consistently. This identifier set should remain together wherever the record is compared or transferred between databases. Keeping the CAS, CID, formula, SMILES, and InChIKey together provides one unambiguous structure reference.
