4-methylpyridazin-3-amine

4-Methylpyridazin-3-amine: Overview and chemical identifiers

4-Methylpyridazin-3-amine is a nitrogen-containing heterocycle in the aminopyridazine class. Its structure comprises a pyridazine ring bearing an exocyclic amino group at position 3 and a methyl group at position 4. The compound is identified by CAS 90568-15-3. Checking the CAS number alongside the molecular structure helps distinguish it from positional isomers and other pyridazine derivatives.

Names, synonyms and CAS 90568-15-3

The IUPAC name is 4-Methylpyridazin-3-amine. The alternative name 3-amino-4-methylpyridazine describes the same substitution pattern, while 4-methyl-3-pyridazinamine is another catalog synonym. All three names refer to the structure assigned to CAS 90568-15-3. A synonym should still be checked against the CAS number or a structure identifier, since changing the position of either substituent gives a different compound.

Molecular structure and chemical properties

The molecular formula is C5H7N3, and the average molecular weight is 109.13 g/mol. The six-membered aromatic ring contains two adjacent nitrogen atoms, and the exocyclic primary amino group provides the third nitrogen. One SMILES representation is CC1=C(N)N=NC=C1. The standard InChI is InChI=1S/C5H7N3/c1-4-2-3-7-8-5(4)6/h2-3H,1H3,(H2,6,8), and the InChIKey is WDTVJTBXOFGSJT-UHFFFAOYSA-N. No stereochemical descriptor is required for this structure. Physical form, storage conditions, and hazard information should be taken from the SDS and documentation for the specific product rather than treated as universal molecular properties.

Applications and research use

Chemical catalogs classify 4-Methylpyridazin-3-amine as a heterocyclic organic building block. Its pyridazine core and exocyclic amino group make it relevant to synthetic route development involving nitrogen-containing scaffolds. Chemists may evaluate the amino group as a site for derivatization, but the feasibility of a transformation depends on the reagents, conditions, and target structure. The compound's identifiers do not establish any biological effect, pharmacological activity, or therapeutic application. Such claims require direct supporting literature or experimental evidence and should not be inferred from research on other aminopyridazine derivatives.

Sourcing and supplier selection on ChemSpace

ChemSpace provides a marketplace interface for finding offers from independent suppliers; it is not the manufacturer of 4-Methylpyridazin-3-amine. When sourcing CAS 90568-15-3, users should confirm that the name, molecular formula, and structure identifiers agree across the listing and supporting documents. Supplier selection should be based on the current offer, analytical specification, batch-specific CoA, SDS, and relevant quality requirements. Handling and storage decisions should follow the applicable supplier documentation. This reduces the risk of confusion with positional isomers while keeping time-sensitive commercial details out of the compound description.
