Chemical Structure
Description
The molecular framework of 5,6-Dihydro-4H-cyclopenta[c]thiophene-1-carbaldehyde (C8H8OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5,6-Dihydro-4H-cyclopenta[c]thiophene-1-carbaldehyde (CAS 1782777-52-9), molecular formula C8H8OS and molecular weight 152.21 g/mol, is a CATO reference standard with documented purity and traceability.
