3-Fluoro-6-methoxypyridazine

3-Fluoro-6-methoxypyridazine is the compound identified by CAS Registry Number 1934842-49-5 and molecular formula C5H5FN2O. Its identity has been cross-checked against PubChem CID 92133191. The verified structure is represented by the SMILES string COC1=NN=C(C=C1)F and the InChIKey KQJOYRAZBSRCFW-UHFFFAOYSA-N. These identifiers describe a pyridazine ring bearing fluoro and methoxy substituents and distinguish this record from related pyridazine derivatives with different substitution patterns.

This page refers only to the neutral molecular entity encoded by the cited structure identifiers. The molecular formula, PubChem CID, SMILES and InChIKey are presented as one linked identity set for comparison with a structure drawing or external chemical database. The identifier set should be reviewed together because a similar name can refer to a different substitution pattern or chemical entity. The fluoro and methoxy positions remain part of the exact identity, and related pyridazine compounds should not be treated as interchangeable without a structure-level comparison.

For a quotation or custom-synthesis discussion, send Rlavie the exact compound name, CAS number, requested quantity and any controlling structure file. Cite PubChem CID 92133191 or the verified InChIKey so the ring substitution pattern can be checked directly. Rlavie can compare the submitted target with the cited public identity before providing request-specific information. This listing defines chemical identity and connectivity only and does not establish commercial conditions. Keeping the complete identifier set in correspondence reduces ambiguity during review.
