tert-Butyl 2-iodo-6,7-dihydropyrazolo[1,5-a]pyrazine-5(4H)-carboxylate corresponds to CAS 1823835-34-2 and molecular formula C11H16IN3O2. PubChem resolves the number to one entry, CID 121229919, with molecular weight 349.17. Its graph is recorded as SMILES CC(C)(C)OC(=O)N1CCN2C(=CC(=N2)I)C1, and InChIKey DIQSCMZKTRUXBO-UHFFFAOYSA-N identifies the same single component.
The fused pyrazolo[1,5-a]pyrazine framework contains three nitrogens. Iodine is attached at position 2, and the 6,7-dihydro notation records the saturated portion visible in the SMILES. At ring position 5, the nitrogen is bonded to a carboxylate whose oxygen carries a tert-butyl group. Those two ester oxygens and the fused-ring hydrogenation state account for features that a shortened “iodopyrazolopyrazine” label would omit. PubChem does not assign a defined stereochemical layer to this molecular graph.
An identity inquiry to Rlavie should include CAS 1823835-34-2, the complete fusion and hydrogenation name, and the requested quantity. Send a MOL or SDF structure file for comparison with PubChem CID 121229919, the stated SMILES, and InChIKey DIQSCMZKTRUXBO-UHFFFAOYSA-N. The review should confirm the 2-iodo position, the 5-carboxylate connection, the tert-butyl ester, and the 6,7-dihydro framework before request-specific information is evaluated. Formula C11H16IN3O2 establishes composition but cannot encode the fused-ring numbering or show which ring nitrogen bears the carbonyl connection. The full identifier set preserves each of these structural details.
