PubChem records 5-(4-Methylphenyl)-3-pyridinecarbaldehyde under CID 18472620 and CAS 229008-16-6. Its formula is C13H11NO, with SMILES CC1=CC=C(C=C1)C2=CN=CC(=C2)C=O and InChIKey ANPGUJZUWRYNKV-UHFFFAOYSA-N. “5-p-tolylpyridine-3-carbaldehyde,” the current catalog wording, is an explicit PubChem synonym for the same graph.
The pyridine ring carries a carbaldehyde carbon at position 3 and an aryl substituent at position 5. That aryl group is a phenyl ring bearing methyl para to its pyridine attachment; “p-tolyl” is the common short form of “4-methylphenyl.” The two rings, aldehyde carbon, and methyl carbon total thirteen carbons in C13H11NO. The sole nitrogen belongs to pyridine and the sole oxygen to the aldehyde. PubChem encodes one neutral molecule, without a disconnected component or stereochemical marker. Keeping both pyridine locants and the para methyl relationship visible prevents confusion with a different tolyl orientation or aldehyde position.
For a record-specific Rlavie inquiry, provide CAS 229008-16-6, CID 18472620, the requested quantity, and request-specific information. If a structure drawing is central to the request, attach a MOL or SDF structure file and confirm the 3-aldehyde, 5-aryl, and para-methyl connections against the official SMILES. InChIKey ANPGUJZUWRYNKV-UHFFFAOYSA-N offers a compact final comparison. Those references allow the message to be associated with this exact biaryl aldehyde rather than another methylphenyl pyridine isomer.
