PubChem CID 87817 is the verified record for 4-Amino-6-methyl-3-(methylthio)-1,2,4-triazin-5(4H)-one. The compound is referenced by CAS 18826-96-5 and has molecular formula C5H8N4OS. PubChem expresses the graph as SMILES CC1=NN=C(N(C1=O)N)SC and InChIKey QGWGENIBCSVSNQ-UHFFFAOYSA-N. Its inverted-index title and the forward-order name are both listed for the same CID.
The six-membered 1,2,4-triazine framework contains three ring nitrogen atoms and three ring carbons. A carbonyl occupies position 5, a methyl group is attached at position 6, and the sulfur-linked methyl group is at position 3. The amino substituent at position 4 supplies the fourth nitrogen in C5H8N4OS. “Methylthio” and “methylsulfanyl” are alternate labels for the same S–CH3 connection encoded in the SMILES. The official graph is a single neutral component, with no separate counterion and no stereochemical descriptor. Reordering the index-style title does not alter these locants or bonds.
For a focused inquiry, quote CAS 18826-96-5 and retain the 4H-one notation together with all three substituent locants. Add the requested quantity, contact details, and any question about the identity record. CID 87817 or InChIKey QGWGENIBCSVSNQ-UHFFFAOYSA-N offers an independent check when the name has been reformatted by another database. Rlavie can then connect the message to the intended methylthio triazinone rather than a tert-butyl analogue, another triazine isomer, or a structure with sulfur bonded at a different position.
