2,5-pyrazinedicarbonitrile

2,5-pyrazinedicarbonitrile is the CAS 31722-48-2 identity with formula C6H2N4 and PubChem CID 14832627. PubChem lists molecular weight 130.11. The page’s recorded SMILES, C1=C(N=CC(=N1)C#N)C#N, matches the official structure, while InChIKey JVOPXXDHVVCVIJ-UHFFFAOYSA-N supplies its fixed-key representation.

The central pyrazine ring contributes two ring nitrogens. A nitrile group occurs at position 2 and another at position 5, yielding two C#N segments in the SMILES. This placement is part of the name rather than a generic formula statement. The two hydrogens in C6H2N4 remain on the unsubstituted ring positions, which helps separate this molecular graph from other pyrazinedicarbonitrile positional arrangements. The explicit ring numbering in the systematic name is retained in the identity review to prevent a positional isomer from being substituted by name alone.

For a Rlavie inquiry, reference CAS 31722-48-2 together with the full name 2,5-pyrazinedicarbonitrile and the requested quantity. If a chemical structure file is supplied, include a MOL or SDF version for comparison. The submitted graph can be checked against PubChem CID 14832627, SMILES C1=C(N=CC(=N1)C#N)C#N, and InChIKey JVOPXXDHVVCVIJ-UHFFFAOYSA-N before request-specific information is addressed. Mention both nitrile positions in the request, because the 2,5 arrangement is the identity captured by this page. The pyrazine ring must remain the central scaffold.
