CAS 1206968-88-8 resolves in PubChem to CID 59620006, titled (5-Bromo-3-chloropyridin-2-yl)methanol. The associated molecular formula is C6H5BrClNO. PubChem represents the compound with SMILES C1=C(C=NC(=C1Cl)CO)Br and InChIKey LNWKQNPETXOPTH-UHFFFAOYSA-N. Those values agree exactly with the formula and structural representation attached to this catalog identity.
Reading from the pyridine numbering in the name, the methanol-bearing side chain is attached at position 2, chlorine occupies position 3, and bromine occupies position 5. The ring contributes one nitrogen atom; the hydroxymethyl fragment contributes the oxygen atom. Six carbons and five hydrogens complete the stated composition. Neither structural notation introduces a disconnected fragment, so the verified record does not describe a separate salt component. Parentheses in the systematic name clarify that the methanol carbon is attached through the pyridin-2-yl fragment.
This substitution pattern cannot be inferred from formula C6H5BrClNO alone, since positional isomers can share that composition. CID 59620006 anchors the exact arrangement, and the SMILES traces where the chloro, bromo, and hydroxymethyl groups connect to the heteroaromatic ring. CAS 1206968-88-8 gives the corresponding registry-style reference, while InChIKey LNWKQNPETXOPTH-UHFFFAOYSA-N offers a concise comparison key. Together, the full name and four identifiers define this particular 2-hydroxymethyl, 3-chloro, 5-bromo pyridine connectivity without collapsing it into a generic halogenated pyridyl methanol label.
