Chemical Structure
Description
The molecular framework of 4-(Methoxycarbonyl)tetrahydro-2H-pyran-4-carboxylic acid (C8H12O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
4-(Methoxycarbonyl)tetrahydro-2H-pyran-4-carboxylic acid (CAS 923020-93-3) is a high-purity analytical reference standard with the molecular formula C8H12O5 and a molecular weight of 188.18 g/mol.
