Chroman corresponds to CAS 493-08-3, molecular formula C9H10O, and molecular weight 134.17. The registry number resolves to one PubChem compound, CID 136319. PubChem records SMILES C1CC2=CC=CC=C2OC1 and InChIKey VZWXIQHBIQLMPN-UHFFFAOYSA-N for the verified structure. The graph contains one neutral component and carries no defined stereochemical layer.
Chroman consists of a benzene ring fused to a six-membered oxygen heterocycle containing two saturated carbon atoms. The SMILES shows oxygen within the ring rather than as a hydroxy substituent and accounts for all nine carbons and ten hydrogens in C9H10O. PubChem's IUPAC name is 3,4-dihydro-2H-chromene. Its synonym response also associates the alternate wording 3,4-dihydro-(1H)-benzopyrane with this same CAS and CID. Choosing the concise preferred Title Chroman removes the hydrogen-locant discrepancy while retaining the exact verified molecular graph.
When submitting an inquiry to Rlavie, state Chroman, CAS 493-08-3, and the requested quantity, and attach a MOL or SDF structure file. The fused benzene–oxygen-ring connection can then be compared with PubChem CID 136319, SMILES C1CC2=CC=CC=C2OC1, and InChIKey VZWXIQHBIQLMPN-UHFFFAOYSA-N before request-specific information is discussed. The identity check should confirm which two heterocyclic carbons are saturated and that oxygen is part of the ring. Formula C9H10O alone does not encode those features and could correspond to a different connectivity.
