2,3-Dimethylfuran

2,3-Dimethylfuran is identified by CAS 14920-89-9 and molecular formula C6H8O. PubChem resolves the CAS number to CID 34337 with molecular weight 96.13. The recorded product name agrees with the PubChem Title, and the structure is represented by SMILES CC1=C(OC=C1)C. InChIKey FJSKXQVRKZTKSI-UHFFFAOYSA-N provides a compact identifier for the same molecular record.

The structure contains a five-membered furan ring, whose oxygen atom is part of the ring. Methyl groups are attached to the adjacent 2 and 3 positions, accounting for the two terminal C groups in the SMILES. The remaining two ring carbons carry hydrogen. This positional description distinguishes the record from other dimethylfuran arrangements that share formula C6H8O but have different connections. The InChI records the ring sequence explicitly, so the assigned methyl locations can be checked without relying on a product-name abbreviation.

For an exact inquiry, provide Rlavie with CAS 14920-89-9, the complete name 2,3-Dimethylfuran, and the requested quantity. A MOL or SDF structure file can be included when a structural comparison is needed. Rlavie can compare that file with PubChem CID 34337, the stated SMILES, and InChIKey FJSKXQVRKZTKSI-UHFFFAOYSA-N before request-specific information is considered. Naming both ring positions in the message avoids confusing this record with another dimethylfuran isomer.
