3-Iodopyridazine

3-Iodopyridazine is the compound identified by CAS Registry Number 65202-53-1 and molecular formula C4H3IN2. Its identity has been cross-checked against PubChem CID 11298682. The verified structure is represented by the SMILES string C1=CC(=NN=C1)I and the InChIKey NNXBSBHTRNCQQS-UHFFFAOYSA-N. These identifiers describe a pyridazine ring bearing iodine at the 3-position and distinguish this record from other iodinated diazines or positional isomers.

This page refers to the neutral molecular entity encoded by the cited structure identifiers. The molecular formula, PubChem record, SMILES and InChIKey are provided together so that researchers and purchasing teams can compare the requested identity with their own specification, drawing or internal material code. The identifiers should be considered as a linked set: a request based only on a shortened name may be ambiguous, while the CAS number and structure keys provide a more precise reference.

For a quotation or custom-synthesis discussion, please send Rlavie the exact compound name, CAS number, requested quantity and any analytical documentation requirements. If a particular structure drawing, specification or reference standard must be followed, include it with the inquiry for technical review. Availability, lead time, deliverable documentation and project conditions should be confirmed in Rlavie’s written response before an order or synthesis project is placed.
